Add centralized DB helper; fix legacy mysql_error() landmines

Browse Source 
- includes/db.php: shared mysqli connection + parameterized query helpers
  (pqs_db/pqs_exec/pqs_rows/pqs_row/pqs_val), targets PHP 7.4+.
- Replace 11 mysql_error() calls (undefined function on PHP 7+) with
  mysqli_error($link) / mysqli_connect_error() across getFSgame, getFSplayers,
  config, callsign, console. Only affected already-failed error paths.
