chore(bruno): add multi-library dev setup with scan-all and folder requests

Update NewDevDBSetup collection to create Ebook, Comic, and Manga
libraries with separate IDs (ebook_library_id, comic_library_id,
manga_library_id) instead of a single library_id.

- Fix CreateComicLibrary and CreateMangaLibrary to use correct
  names, descriptions, and types instead of duplicating Ebook values
- Update NewDB.sh to run the full setup sequence: register user,
  create all three libraries, add folders, then scan all
- Add AddEbookLibraryFolder, AddComicLibraryFolder, and
  AddMangaLibraryFolder requests with per-type subfolder paths
- Add ScanAllLibraries request using bru.sendRequest() to scan
  each library sequentially via the /api/scanner/scan endpoint
- Update Get Libraries (Admin) to save all three library IDs
- Update List Media Items requests to use ebook_library_id
- Rename library_id to ebook_library_id in Create Library and
  Add Library Folder requests
- Add comic_library_id and manga_library_id to environment
