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
