Item #4: centralize timezone, collapse the 16 pod branches to loops

- includes/db.php now defines PQS_TIMEZONE and sets it on include; the 9 files
  that hardcoded date_default_timezone_set('America/Chicago') drop the call
  (main pages already load db.php; display includes now require it).
- console.php: pod load and the 16 pod-checkbox lines collapsed into loops over
  a $pods array (fixed 16 kept - hardware max). Output unchanged.

Verified: timezone resolves to America/Chicago via the constant; console commit,
config update, and pod-checkbox rendering all correct; registration suite green.
