feat(entry): operator-issued entry + exit plate-swap reconciliation

Two halves of one anti-fraud design.

(A) Operator-issued entry — when the physical entry button is broken, an
operator can issue an entry ticket so a real car isn't blocked out of the lot.
This hands the operator-adversary a mint, so it is:
  - PRESENCE-GATED like the physical button: a real car must be present (radar/
    loop AND camera busy). Enforced BOTH sides — the server re-checks current
    presence so a direct POST can't bypass a disabled button; no presence loop
    => feature unavailable; a no-presence attempt signs an anomaly.
  - FLAGGED: vehicle_entry source=manual + operatorInitiated + operator, PLUS a
    companion entry.operatorIssued anomaly (the adversary path always leaves a
    red-flag row).
  - capacity-OVERRIDE allowed but stamped lotFull (a broken button mustn't trap
    a legit car).
  New session:create permission (migration 0019 -> operator role, admin-
  revocable), POST /api/entry/issue (open-shift gated), EntryFlow.
  issueForOperator; the fraud-critical print->sign->open->snapshot sequence is
  factored into one shared #issueTicket (button + operator). UI: the entry
  BarrierLight becomes a clickable issue-control when presence+permission+shift
  meet (confirm -> issue).

(B) Exit plate-swap reconciliation — defends the ticket-swap fraud the mint
enables (paid car let out on a fresh $0 ticket, original ticket lingers
"inside", occupancy drifts up by phantom cars). The plate is the invariant:
ExitFlow.#reconcilePlateAtExit compares the exiting plate against all OPEN
sessions' entry plates, EXACT + HIGH-CONFIDENCE only (>=0.85; a fuzzy read never
gates — ANPR is advisory). On a match under a DIFFERENT ticket:
  - BOOTH path: returns swap_suspected + signs exit.plateSwapSuspected; the
    pay/exit modal shows a red warning + "Override & release" (override signs an
    attributed exit.plateSwapOverride). Flag+override, never a silent hard block
    (exit fails-open; a plate is never the sole gate).
  - READER path (no operator): log-only anomaly + fail-open.
  Extended BoothExitResult + /api/exit (override); boothExit client returns a
  structured swap result.

Verified: full monorepo build/lint/test green (229 server tests incl. 4 new:
hold-on-swap, override-releases-with-attribution, low-confidence-no-warning,
own-plate-no-warning). New wiki: operator-issued-entry.md +
plate-reconciliation.md; cross-linked from entry-exit-points, capacity-
occupancy, index. Preserves "a plate never OPENS a barrier alone — and now never
TRAPS a car alone either."
