feat(permissions): per-desk till guards, jobs in the role composer, permission-scoped live feed; role reassignment applies without re-login

Permissions matrix rethink (wiki/decisions/venue-modules.md §"Permissions matrix",
open-questions #16) — the grid stays the enforcement layer:

- Move 1: each desk's money is guarded by that desk's own permissions. Manifest
  tillGuards {read, shift, cash}: booth = shift:read / shift:create / drawer:create
  (unchanged), carwash = carwash:read / carwash:cash (new). Shift + drawer routes
  resolve the guard FROM THE TILL (requireTill); a wash role holds no shift:* and cannot
  touch the booth by construction. Replaces the session:read borrowing (tillPermission).
  /api/shift/tills lists the role's readable tills with canWork; history/movements
  without a till filter return the union of readable tills.
- Move 2: jobs — manifest permission bundles (booth-operator, booth-supervisor,
  merchant, wash-operator) as one-click chips in Setup → Roles, with "mixes desks" and
  "partial job" lints (warnings, never blocks).
- Move 3: the live WebSocket admits any watch permission (event/session/device read or
  a module's feedPermission) and filters every push per role; report:read is the
  reports screen only.

Auth: the token's roleId is only a hint — refreshRole() after every jwtVerify resolves
the user's CURRENT role (cached, bumped on role/user writes), so reassigning a user's
role applies on the next request and a deleted user's session ends with 401.

Tests: till guards + look-only role, feed rules, every job's permissions exist, role
reassignment without re-login. 353/353.
