- Pending/uploading rows get a cancel button; every cancel is confirmed
in a dialog and the source file is always kept — only a confirmed
upload deletes originals. The in-flight HTTP transfer aborts
immediately (async OkHttp call instead of blocking execute()).
- Enqueue refuses content whose SHA-256 is already pending/uploading,
so sharing or picking the same file twice no longer uploads it twice
in parallel (content URIs are opaque; the hash is the identity).
- Cancel/finish races resolved with conditional DB updates: a cancel
landing mid-flight keeps the source; a cancel after completion is
refused with a toast instead of flipping a finished row.

- Delete the source file once an upload is confirmed (best-effort: SAF
picks get a persisted read+write grant and are removed; read-only
shared streams are left in place). Cache copy always removed. A removed
source shows as 'removed from phone'.
- Distinguish duplicates: a HEAD (or the server's 200 existed) marks the
item 'Duplicate · already on server' — content is never re-sent or
overwritten, since the name IS the sha256. Different content = different
hash = a new file, not a duplicate.
- 'Clear history' app-bar button clears finished/duplicate/failed rows.
- Register as an 'Open with' target (ACTION_VIEW, content/file) in
addition to the existing share-sheet target.
- Room schema v2 (destructive fallback; queue is ephemeral).
