MechaCat02 8d34132883 bugfix: security & correctness bundle (0.34.1) ...

Five fixes bundled into one release:

- preserve user-attached tags across crawler upserts
  (repo::crawler::sync_tags now scopes to added_by IS NULL; orphaned
  attachments from deleted users are reaped as crawler-owned)
- gate manga PATCH and cover endpoints on uploaded_by (require_can_edit
  in api::mangas; non-NULL uploaded_by must match the caller)
- equalise login response time across user-existence branches
  (run argon2 against a OnceLock-cached dummy hash on the no-user
  branch so timing doesn't leak username existence)
- crawler download defences (SSRF allowlist of host literals
  including IPv4-mapped IPv6 ranges, 32 MiB streamed size cap,
  reject non-whitelisted image types, three-way chapter-probe
  classifier replaces the binary #avatar_menu check)
- tighten validation and clean up dead unload path
  (attach_tag + create_token enforce 64-char caps; LocalStorage
  rejects NUL bytes explicitly; reader flushFinalProgress drops
  the always-405 sendBeacon path)
