feat: add series status, improve providers & e2e tests

- Add series status concept (ongoing/ended/hiatus/cancelled/upcoming)
  with normalization across all providers
- Add status field to series_metadata table (migration 0033)
- AniList: use chapters as fallback for volume count on ongoing series,
  add books_message when both volumes and chapters are null
- Bedetheque: extract description from meta tag, genres, parution status,
  origin/language; rewrite book parsing with itemprop microdata for
  clean ISBN, dates, page counts, covers; filter placeholder authors
- Add comprehensive e2e provider tests with field coverage reporting
- Wire status into EditSeriesForm, MetadataSearchModal, and series page
