* fix: Catch mysqli_sql_exception in DB fallback handlers for fresh Docker installs

On a fresh Docker install with an empty database, the ospos_sessions
table doesn't exist yet. The CSRF filter triggers session initialization
before the login/migration page can be reached.

The existing code in Session.php, OSPOS.php, and MY_Migration.php
catches DatabaseException, but the MySQLi driver throws
mysqli_sql_exception (which extends RuntimeException, not
DatabaseException) when the table doesn't exist. This causes an
unhandled exception resulting in HTTP 500.

Fix: Change all three catch blocks from  to
 so that mysqli_sql_exception and any other unexpected
database errors are caught, allowing the app to fall back gracefully:

- Session.php: Falls back to FileHandler so sessions work without DB
- OSPOS.php: Falls back to empty settings so config loads work
- MY_Migration.php: Falls back to version 0 / false so the migration
  check passes gracefully

This allows the login page with migration UI to be served on first
access, so the initial schema migration can run.
