feat(book-dock): expose Book Dock folder as a configurable drop zone (#64)

* feat(docker): expose Book Dock folder as a configurable drop zone

Add support for an external book drop folder that users can bind-mount
into the container via the BOOK_DROP_HOST_PATH env var. Files copied or
moved into this folder are automatically picked up and ingested by the
existing Book Dock file watcher.

- docker-compose.yml: add BOOK_DROP_HOST_PATH volume override so the
  book-dock path is separately bind-mountable
- .env.example: document BOOK_DROP_HOST_PATH with an example NAS path
- AppInfoResponse: add bookDockPath so the UI can show the
  container-internal path admins need to bind-mount
- AppInfoService: compute and return bookDockPath from storage config
- BookDockSettings: display drop folder path with BOOK_DROP_HOST_PATH hint
- useAppInfo: expose bookDockPath ref from the app-info API response
- README: document the optional drop folder in the quickstart section

When BOOK_DROP_HOST_PATH is unset, the volume defaults to
./data/app/book-dock, preserving full backward compatibility.
No watcher code changes required - the watcher already watches
the correct container-internal path.

Closes #58

* fix(book-dock): resolve symlink paths so rescan stays idempotent

BookDockWatcherService and BookDockIngestService were building
bookDockPath with path.join(), which preserves symlinks. `@parcel/watcher`
resolves symlinks internally when reporting events (using realpath), so the
absolutePath values stored by watcher events and the paths computed by
walkAndIngest during rescan never matched. This caused findByAbsolutePath
to always return undefined on rescan, creating duplicate DB records for
every file already tracked via a watcher event.

Fix: both services now call `realpath(bookDockPath)` in
onApplicationBootstrap (after mkdir), updating the stored path to the
canonical real path that the watcher also uses. Rescan is now idempotent
regardless of symlinks in the data directory.

Verified by E2E test: 3 consecutive rescans produce zero new records.
