PROPFIND walk / diff / GET / PUT mirror with conflicts, per-account state,
BGTaskScheduler background runs, and conflict notifications with Keep local /
Use server. Reviewed by Codex against the Kotlin original; its data-loss
findings are fixed and each has a regression test (fake-server end-to-end
tests, 68 Swift tests total): truncated/unusable PROPFIND answers are never a
manifest, unreadable state aborts the run, server paths can't leave the mirror,
case/Unicode collisions are skipped, atomic downloads, a locally edited file
deleted on the server is kept, '/' scope matching, serialised removal,
tracked/cancellable background runs, per-account conflicts, and sign-out vs
background-off credentials (cancel gains a 'forget' flag).

SwiftUI folder picker in the extension (WebDAV PROPFIND), account shared via
a Keychain group, upload on a background session that outlives the extension
and is finished by the app. The inbox + notification hand-off remains as the
fallback (no account / 'choose later'). Shared code moves to ios/Shared.

Swift implementation of the upload_service/download_service channels:
background PUT/GET against the account's WebDAV root, one summary local
notification per batch, Downloads visible in the Files app. Pure helpers
covered by RunnerTests.
