A recent change (#4407) made Android's "Open with Readest" (VIEW intent,
used by Telegram and similar apps) always open the file as a transient
book: into the reader but never written to the library, with its filePath
pointing at the original content:// URI. Once that temporary URI grant
dies the book can no longer be reopened, so the user has to re-share it
from the source app every time.
Make the transient behavior an opt-out gated by the existing
autoImportBooksOnOpen setting, and surface it on mobile:
- The VIEW handler now consults the setting via a new shouldOpenTransient
predicate. When auto-import is on it falls through to the same library
ingest path as a share-sheet SEND (full ingest plus cloud upload); when
off it keeps the transient open.
- Read the setting from disk in the handler rather than the settings
store, since on a cold-start "Open with" the store is not hydrated yet
and would wrongly fall back to a transient open.
- Show the "Auto Import on File Open" toggle on mobile (was desktop only).
- Default autoImportBooksOnOpen to true on mobile so shared files persist
and sync by default; the desktop default is unchanged.
