fix: plugin locale merge re-runs on HMR; API Key form allows Personal

- locale-merger: drop the module-level dedup Set. addLocale is
  idempotent, and the guard made HMR-added plugin locale keys
  silently skipped — strings like organizations.members.selectUsers
  stayed unresolved until a full dev-server restart.
- api-keys form: pass allowPersonal: true to CreateOrgScopeField so
  admin in Platform-wide mode can target their own Personal Org when
  creating a key (unlike infra resources where Personal doesn't fit).
