Fix startup failures at info log level with robust error handling

The addon was failing to start at info log level due to strict error
handling (set -e) that caused exits when utility scripts failed to load.

Changes:
- Add comprehensive error handling for all script sourcing
- Use 2>/dev/null to suppress debug output that breaks info mode
- Check for function existence before calling them
- Convert fatal errors to warnings and continue startup
- Add detailed dashboard startup validation and logging
- Export LOG_LEVEL for use in child scripts

This allows the addon to start successfully at both info and debug
log levels, with graceful fallbacks when utilities fail to load.
