Add an admin-controlled debug mode that captures PHP errors of all
players into var/log/debug-players.log, to hunt remaining PHP 8.3 bugs
from real play sessions. Fully transparent to players: no redirect, no
gameplay change, errors are never displayed.
- DB: new debug_log table (one row), mirroring the maintenance pattern.
- Database: getDebugMode()/setDebugMode()/setDebugSettings(), defensive
when the table is absent (no blank page).
- Session: register a custom error + shutdown handler when enabled; the
handler runs even when php.ini error_reporting masks warnings/notices,
so capture is complete without a Docker rebuild. Auto-disables after a
configurable window.
- DebugErrorLogger: size-capped file with a single .log.1 rotation,
honours the @ operator, never throws.
- Admin: new "Debug Error Log" page (levels, size cap, auto-off, on-page
viewer, clear, download) + debugLog action mod.
- Menu: admin-only quick on/off widget (TZ_DEBUG_ON/OFF, EN/FR/RO).

This is a very naive and primitive logger of user requests to the game.
To be used on systems where access to webserver's log data is not
available (especially if the webserver doesn't store POST data as well).
