fix(e2e): fix admin tag test (use existing tag) and annotation locator

- Admin tag test: "Familie" never existed in the database; use "Fest"
  which is a real seeded tag, with a matching rename-back to restore state
- Annotation hash test: the broad `[data-testid^="annotation-"]` locator
  also matched `annotation-side-panel` (always in DOM, even when
  off-screen); extend the :not() exclusion list to cover it
