refactor: Move log directory configuration to Application section

- Move LogDirectory from Logging section to Application section in appsettings.json
- Update Program.cs to read from Application:LogDirectory instead of Logging:LogDirectory
- Fix JSON schema validation warning for non-standard Logging properties
- Application section now holds custom application-specific settings
- Standard Logging and Serilog sections remain clean and schema-compliant
