feat(booth): cancel wrongly-printed ticket (signed void) + refused-vs-anomaly display; fix CI uv

Cancel a misprinted/test/wrong-vehicle ticket via a SIGNED `void` event — the
vehicle_entry is never edited/deleted (append-only). VoidFlow appends void{
voidedEntryRef, voidReason, operator, reasonCode:"void.ticketCancelled" }; route
POST /api/tickets/void gated event:void + open shift; reason REQUIRED. Refuses a
subscription / already-exited / already-voided / paid ticket (refund out of scope).
The void folds the session CLOSED everywhere it's counted — occupancy (count +
reserved spots), pay-station (lookup/activeSessions), exit-flow (#sessionFor), and
reports (excluded from entries) — so a voided car stops occupying a spot, can't be
paid/exited, and doesn't inflate "cars entered". No barrier action. Booth UI: a
"Cancel ticket" action in the pay/exit lookup modal (transient + unpaid + open;
gated on event:void) with a preset-or-free reason prompt.

Reclassify the Live feed: refused-action events (exitRefused/entryRefused/
permitRefused — e.g. a double card-scan, at-capacity subscriber, exit on a closed
session) are benign warnings, not red anomalies. event-detail.tsx now shows them as
amber REFUZUAR/REFUSED, reserving red ANOMALI for genuine red-flags. Display-only —
no ledger change, so historical events reclassify too.

CI: install uv + sync vision deps before the Turbo run. @parking/vision's lint/
typecheck/test shell to `uv run …`, but CI set up only Node+pnpm, so `uv run ruff`
failed ("uv not found") and broke the whole Turbo run. The Python checks pass once
uv provisions the toolchain.

- new: void-flow.ts (+ tests, 8) ; occupancy void-fold test
- shared: reason code void.ticketCancelled ; both web catalogs (sq/en parity)
- wiki: parking-session (ticket-void folds + guards, refused/anomaly split), log
