Panel no longer depends on the user-managed MariaDB service.
SQLite at /var/lib/novacpx/panel.db runs independently so the
control panel stays up even when MariaDB is stopped.
- DB.php: switch to sqlite: DSN, add SQL translator (ON DUPLICATE KEY,
DATE_ADD/DATE_SUB INTERVAL, NOW(), UNIX_TIMESTAMP(), IFNULL)
- Core.php: replace DB_HOST/NAME/USER/PASS with DB_PATH constant
- schema.sql: full SQLite syntax, add TOTP columns to users table
- _branding.php: use sqlite: PDO, datetime('now') for session check
- install.sh: apt install sqlite3, create SQLite DB instead of MySQL DB
- tools/migrate-to-sqlite.sh: one-shot migration script for existing installs
