Fix: Removing the key request on export page.

- add a protected health.php page for config, XMLTV and M3U diagnostics
- add shared admin/config helpers for authenticated internal tools
- add a styled 24h export page designed for PDF/print output
- add browser-side PNG export for the daily schedule
- update README with the new admin tools
