Improve build reliability, query perf, and documentation

- Add build-error-resolution.md guide for CS0006 and IDE analyzer issues
- Add rebuild-solution.ps1 script for clean/reliable builds
- Suppress noisy IDE/StyleCop warnings in .editorconfig
- Optimize BaseItemRepository grouping queries to use Min(Id) instead of FirstOrDefault, avoiding correlated subqueries and greatly improving DB performance
- Add database-query-optimization.md explaining query changes and tuning
- Enable EF Core SQL query logging, sensitive data, and detailed errors when log level is Debug (ServiceCollectionExtensions, logging.json)
- Update readme with SQL logging instructions
- Clarify git commit/ignore guidance and improve inline documentation

 If you get the error: `Run "dotnet tool restore" to make the "dotnet-ef" command available.` Run `dotnet restore`.
 
 in the event that you get the error: `System.UnauthorizedAccessException: Access to the path '/src/Jellyfin.Database' is denied.` you have to restore as sudo and then run `ef migrations` as sudo too.

+# Database Query Logging
+
+To enable SQL query logging for debugging purposes, you need to configure the logging level in your `logging.json` file located at `Resources/Configuration/logging.json`.
+
+## Enable SQL Query Logging
+
+To see all executed SQL queries in the logs, change the logging level for Entity Framework Core database commands:
+
+```json
+{
+    "Serilog": {
+        "MinimumLevel": {
+            "Default": "Information",
+            "Override": {
+                "Microsoft": "Warning",
+                "System": "Warning",
+                "Microsoft.EntityFrameworkCore.Database.Command": "Debug"
+            }
+        }
+    }
+}
+```
+
+When `Microsoft.EntityFrameworkCore.Database.Command` is set to `Debug`, the following will be logged:
+- All SQL queries being executed
+- Query parameters (including sensitive data)
+- Query execution times
+- Detailed error messages
+
+## Logging Levels
+
+- **Debug**: Logs all SQL queries with parameters and execution details
+- **Information**: Logs queries without parameters (default setting in the configuration)
+- **Warning**: Only logs slow queries and warnings
+- **Error**: Only logs database errors
+
+**Note**: Query logging with sensitive data is automatically enabled when using Debug level. Be careful not to expose sensitive information in production environments.
