test(e2e): realign mocks + assertions with the current API and OCR-era UI

The route-mocked E2E specs had drifted from the app they exercise, so
each rendered an empty/500 page and timed out on missing elements:

- Manga detail + reader loads now also fetch read-progress/{id} and
  /similar; several specs never mocked them, so the load's Promise.all
  rejected. Add the mocks and fill the manga fixtures out to a real
  MangaDetail (status/alt_titles/authors/genres/tags/... ) so the
  components stop throwing mid-render.
- back-nav + library: widen `read-progress*`/`page-tags` globs — `*`
  doesn't cross `/`, so `/me/read-progress/{id}` fell through to the
  proxy and 500'd; mock the library page-tags pair too.
- manga-list search: wait for the initial load to settle before
  searching so the search fetch can't race the mount-time load.
- reader-chapter-select: assert the shared `chapterLabel` output.
- admin-analysis: the active OCR backend extracts text only, so the
  detail modal shows OCR (no tags/NSFW) and metrics shows tiles +
  trend charts (no by-model) — assert what the OCR-era UI renders.
- profile: assert the wrong-password 401 stays inline (guards the
  fix in the preceding commit) and mock the guest bookmark/collection
  fetches the /profile load maps to the sign-in prompt.
