fix(ci): repair green pipeline — oauth migration, playground e2e, table refresh

- db: generate lore migration 0043 for the oauth_clients.trusted column
  (single ADD COLUMN, no DROP TABLE — safe on D1)
- playground: declare @alepha/test... add missing @playwright/test devDep so
  the playground e2e suite actually runs (it never ran before — yarn only
  exposes a workspace's declared deps' binaries)
- ui(alepha-table): add `refreshSignal` prop for external refetch triggers.
  The table holds `fetch` in a ref (anti-loop), so a changing fetcher
  identity never reloaded it; mutations performed outside row/bulk actions
  (e.g. toolbar upload) had no refresh path.
- ui(admin-files): drive the post-upload reload via `refreshSignal` instead
  of the fetcher deps (which the table ignores by design)
- docs: regenerate $issuer/$realm reference for the signing config field
