Auth page: pure-PHP Authelia ACL parser, NPM-sourced certs tab, watchdog JS fixes, rsync settings layout

- Replace python3/PyYAML Authelia ACL parser with pure PHP (no deps available on Unraid)
- Cert tab now pulls live from NPM API instead of cert_monitor.sh — auto-discovers all managed certs sorted by urgency
- Watchdog page: add missing GB constant and _fmtBytes/_relTime functions that were causing silent render failure
- Rsync settings card: pin to far-right 3 columns (grid-column:6/-1), toggle grid narrowed to 2 columns
- Add CLAUDE.md project context file on /boot for session persistence across reboots
- claude_startup.sh: symlink CLAUDE.md into /root on array start
