feat(tills): per-till activity log, wash bucket on the booth Z-report, wash-desk printer role

Closes the three known follow-ups of the Tills decision (venue-modules.md):

- Activity log per till: `tillOfEvent(type, payload)` in @parking/shared (money events
  by payload till, other events by their owning module's till, everything else booth),
  applied by `/api/events?till=` in SQL and passed by the hub log, the Drawer "today"
  panel and the booth feed (history + live pushes). The events route admits a role that
  holds a module feed permission without event:read and returns only that module's
  event types — the live-socket rule.
- Booth Z-report: `chargesByModuleMinor` sums the chargeLines on the till's payments by
  module; the ticket bucket excludes them (Bileta = parking only); printed
  "Lavazh (në biletë)" only when any was taken. The wash till's slip prints "Lavazh:".
- Printer role `wash-desk`: the wash till's Z-report and vouchers print there, falling
  back to the booth printer; nothing falls back to the desk. `printerRoleOf()` is the
  one reading of the role field (the entry/booth loaders treated any non-booth role as
  an entry dispenser). Footer label "at wash desk".

Also: `GET /api/carwash/settings` opens to carwash:read OR site:read (new
requireAnyPermission) — the Wash operator job could not load the desk's category and
service pickers. Tests for all four; wiki (shift, printer-roles-failover, venue-modules,
log) updated.
