feat(roles): roles remember the jobs they follow (re-appliable), every role edit is signed

Closes the permissions-matrix loose ends (venue-modules.md §Permissions matrix):

- `role_jobs` (migration 0029): a role stores the manifest jobs it was composed from
  (chips on at save + any bundle fully present). `jobById` / `jobsBehind` in
  @parking/shared surface a followed job whose bundle grew past the role in a later
  release; the roles list shows a "behind <job>" badge with a one-click "Update to job"
  (the union, nothing removed) and the editor lints it. Never a runtime union: the grid
  stays the explicit enforcement layer and an update never widens a role without a click.
- Every role create/update/delete appends a `config_change` (`role.<id>`, prev/value =
  name + sorted permissions + jobs, operator); a no-op resave signs nothing. roleRoutes
  now takes the ledger.
- booth-supervisor already carries subscription:*; the stale open note is closed.
