- Add detailed console logs with emoji prefixes for easy filtering
- Log save/load operations in readingPositionService
- Log position restore in ContentPanel with requirements check
- Log Archive tab position loading with article details
- All logs prefixed with component/service name for clarity
- Log shows position percentages, identifiers, and timestamps
- Helps debug why positions may not be showing or syncing
