FIX - Add detailed custom-app debug logging

Enable verbose tracing for custom apps and wire diagnostics through the stack. Sets Config.CustomApps.Debug = true, adds a debug_custom_app logger exposed as SkyPhoneApps.Debug, and instruments client and shared compatibility code (registration, normalization, provider exports, catalog sync, lifecycle hooks, resource stop, and app add/update/remove) with structured debug messages. Frontend sends a debug flag with the catalog and will call back to NUI (custom-app:catalog-debug) when debug is enabled. Tests updated to enable debug and assert fixBlur preservation and NUI catalog ACK handling. This provides detailed traces for exports, registration, catalog sync and lifecycle events.
