feat(booth): overstay sessions, top-up pricing, and session/feed filters

Rework paid-but-grace-expired sessions and add booth filters.

Overstay (was "stuck"):
- Stop silently aging out a paid transient whose walk-back grace lapsed with no
  signed exit. Keep it listed with an OVERSTAY badge — a new parking period began
  (re-parked) or the car is faulty/abandoned; it is not a system fault.
- No free exit: reopenBarrier refuses server-side once a transient's payment grace
  has expired (allow only subscription OR paid-and-within-grace); the UI hides the
  Open-barrier button on overstay rows and routes to the pay/exit modal. Closes a
  hole where a stale payment authorized a free multi-day exit (operator-as-adversary).
- Price the overstay as a NEW period from grace-expiry -> now with its own daily-cap
  ladder, NOT "full stay minus paid" (which a daily cap collapsed to 0 — ticket
  1245791632490 owed ALL 0; now owes its real overstay). quote() gains periodStart +
  overstay; SessionLookup/ActiveSession gain `overstay`. handlePayAndExit charges
  whenever the session is payable (was: only if !alreadyPaid, skipping the overstay).

Filters (new ui/FilterBar): Active Sessions — search + status
(unpaid/paid/exiting/overstay) + transient-vs-subscriber. Live feed — search +
event (entry/exit/pay/void/anomaly) + direction + source (booth=manual vs reader).
All client-side over already-fetched data; matched/total count shown.

i18n parity (sq+en). Wiki: booth-exit-flow updated (overstay model, naming history,
no-free-exit security fix, new-period pricing; open question on grace-renewal noted).
