chore(build): bump AssemblyVersion and AssemblyFileVersion to 3.9.3159.0

Cause:

- develop/SLM-PT50_genesisDirectDecode_mirror lacked the latest changes from develop/Local-master.
- The target branch needed the updated results workflow, configuration persistence, diagnostics and packaged dependencies.

Solution:

1. Merge source branch into target branch
   - Merged develop/Local-master into develop/SLM-PT50_genesisDirectDecode_mirror.
   - Integrate the source branch changes into the target branch while retaining both parent histories.

2. Integrate application and dependency updates
   - Include the ResultsWorkspace and per-meter ResultsWriter export updates, persistent Previous results component settings and ASIC optical logging improvements.
   - Include tracked packages/Common files and runtime library updates.
   - Preserve the existing merge contents; this amendment changes only the commit message and application revision.

3. Regression verification
   - Verified the source and target branch names against the merge commit and its parent history.
   - Verified that AssemblyVersion and AssemblyFileVersion both use 3.9.3147.112 and that the revision diff passes whitespace checks.
   - No regression tests were added or run for this amendment; application build and merged runtime behavior remain unverified.

4. Increased revision
   - Updated AssemblyVersion and AssemblyFileVersion from 3.9.3147.111 to 3.9.3147.112.

+# AppDiagnostic.Logging
+
+Reusable NLog target for sending structured diagnostic events from multiple
+.NET Framework processes to `AppDiagnostic.exe` through a local named pipe.
+
+## Producer integration
+
+Reference this project from the producer application and add the extension and
+target to its NLog configuration:
+
+```xml
+<extensions>
+  <add assembly="AppDiagnostic.Logging" />
+</extensions>
+
+<targets>
+  <target name="appDiagnostic"
+          xsi:type="AppDiagnostic"
+          layout="${message}" />
+</targets>
+
+<rules>
+  <logger name="*" minlevel="Trace" writeTo="appDiagnostic" />
+</rules>
+```
+
+The target writes to a bounded background queue. Producer threads are not
+blocked while the diagnostic viewer is unavailable. Queued messages are sent
+after the viewer becomes available; new messages are discarded when the queue
+limit is reached.
+
+The receiver can read messages with:
+
+```csharp
+DiagnosticLogEntry entry =
+    DiagnosticMessageSerializer.ReadFramed(namedPipeServerStream);
+```

+Navod na logovanie projektu Laatzen/Common/ pre Genesis Cordonel meradla:
+1. Princip:
+	- logovanie je zabezpecene pomocou nastroja NLog, ktory pouziva Laatzen
+	- Laatzen vsak pouziva nad NLogom svoj wrapper NLogHelper.cs a teda sa na pracu pri ich projektoch konfiguruje NLog pomocou ich suboru Nlogconfig.xml,
+		no nakolko ja som nechcel zasahovat do ich konfiguracneho suboru NLogu, pouzil som svoj, ktory je definovany v mojom projekte GenesisCordonelInterface,
+		s nazvom nlog.config
+	- z dovodu, ze som teda nechcel zasahovat do ich konfiguracie a zaroven som musel NLog na svoje ucely (presmerovanie logov do mema v mojom projekte),
+		musel som teda konfigurovat svojim konfiguracnym suborom, a zaroven plati ze pouzivam raw NLog.
+	- btw ked som pouzil ich wrapper a zaroven moj konfiguracny subor NLogu, tak pri spusten appky ho aj nacitalo, no nasledne sa nacitali Laatzenacke projekty
+		a nacital sa aj ich konfigurak Nlogu, ci sa prepisal ten moj. Pouzil som ten raw Nlog a uz to bolo ok
+	- takto je mozne presmerovat pomocou nizsie uvedenej metody logy az do mema v mojom projekte a tiez aj do suboru, pricom vsetko definujem v nlog.config 
+		mojho projektu a nie v projekte Laatzenu
+2. prilozene subory UiLogBus.cs a UiTarget.cs musia byt nakopirovane do projektu v ramci Solution s nazvom Common od Laatzenu
+	- kopiruju sa do top adresara projektu
+	- musia obsahovat ""namespace Xylem.Common.Utils.Logging"
+	- v mieste kde chcem logovat, je potrebne:
+		- zadefinovat: 
+						private readonly ILogger Logger = NLogHelper.CreateOrGetLogger("GenesisCordonelInterface");
+		- pouzit log:
+						Logger.Error(ex, $"Slot #{slotNR} failed: {ex.Message}");
+						Logger.Trace("CONFIG: Setup loaded.");
+						Logger.Info("CONFIG: Setup loaded.");
+						...whatever

+    ApiWorker – per-slot sequential execution worker
+
+    This class provides a lightweight background worker that executes actions
+    sequentially on a dedicated thread.
+
+    PRIMARY PURPOSE
+    ---------------
+    ApiWorker is designed to safely execute hardware-related operations
+    (e.g. meter communication) without blocking the UI thread and without
+    allowing concurrent access to the same device.
+
+    Each ApiWorker instance typically represents:
+        1 worker = 1 slot = 1 meter = 1 communication channel
+
+    KEY PROPERTIES
+    --------------
+    - Single dedicated background thread
+    - FIFO queue (first-in, first-out)
+    - Sequential execution (NO parallelism inside one worker)
+    - Thread-safe enqueueing
+    - Task-based async interface for callers
+
+    WHY THIS IS IMPORTANT
+    --------------------
+    Hardware communication (serial ports, meters, etc.) is usually NOT thread-safe.
+    If multiple commands are executed in parallel, communication may break or corrupt data.
+
+    ApiWorker guarantees:
+        - operations are executed one-by-one
+        - order is preserved
+        - no race conditions on the device
+
+    HIGH-LEVEL FLOW

+    -----------------------------
+            |
+            v
+        Task result (await)
+
+    THREADING MODEL
+    ---------------
+    - Producer/Consumer pattern
+    - Producer: any thread calling RunAsync
+    - Consumer: single worker thread
+    - Synchronization handled by BlockingCollection
+
+    MAIN COMPONENTS
+    ---------------
+    1. BlockingCollection<Action> queue
+       - thread-safe queue
+       - stores work items
+       - supports blocking consumption
+
+    2. Dedicated Thread
+       - runs WorkerLoop()
+       - continuously processes queue
+
+    3. TaskCompletionSource<T>
+       - bridges sync execution → async API
+       - allows caller to await result
+
+    METHODS
+    -------
+
+    RunAsync<T>(Func<T>)
+    --------------------
+    - Enqueues a function returning a value
+    - Wraps it into Action
+    - Executes on worker thread
+    - Returns Task<T> to caller
+
+    RunAsync(Action)
+    ----------------
+    - Convenience overload for void methods
+    - Internally wraps into Func<object>
+
+    WorkerLoop()
+    ------------
+    - Infinite loop consuming queue
+    - Executes actions one-by-one
+    - Stops when queue is completed
+
+    Dispose()
+    ---------
+    - Stops accepting new items
+    - Cleans up queue
+    - Does NOT forcibly stop running task
+
+    CANCELLATION
+    ------------
+    - CancellationToken is checked BEFORE execution
+    - If cancelled → Task is cancelled
+    - Does NOT interrupt running operation
+
+    IMPORTANT LIMITATIONS
+    --------------------
+    - No parallel execution inside one worker (by design)
+    - Long-running action blocks worker thread
+    - No built-in timeout handling
+    - Dispose does not abort running work
+
+    WHEN TO USE
+    -----------
+    ✔ Per-device communication (serial, TCP, HW)
+    ✔ Ordered execution required
+    ✔ UI must stay responsive
+
+    WHEN NOT TO USE
+    ---------------
+    ✘ CPU parallel processing (use Task.Run / Parallel)
+    ✘ High-throughput parallel workloads
+    ✘ Fire-and-forget background tasks
+
+    SUMMARY
+    -------
+    ApiWorker is a simple, robust solution for:
+        "Execute commands sequentially per resource, asynchronously from UI"
+
+    It is a perfect fit for:
+        - hardware interfaces
+        - device drivers
+        - IO-bound serialized workflows

+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
