Add in-app copy/move, background downloads, and a Favorites tab

- WebDAV MOVE/COPY-backed copy/move for files and folders, with a destination picker (independent nav state so it doesn't disturb the Files tab's browsing position) and a conflict-resolution sheet (overwrite all / keep both / decide per item). - Downloads now use the same foreground-service + notification approach as uploads, surviving app closure. - Favorites is now its own tab (account-wide, via a WebDAV SEARCH query) instead of a Files-tab filter toggle, which couldn't represent favorited items outside the currently browsed folder correctly. - Share sheet restyled to match the app's design language, plus a "share file directly" action via the OS share sheet; details sheet tab icons resized to match the bottom nav.

+/// Shown after a Move/Copy batch comes back with `MoveCopyResult.conflicts`
+/// non-empty (an item with the same name already exists at the
+/// destination) - summarizes every conflict at once rather than prompting
+/// per item as they're hit, and lets the user resolve them all the same
+/// way (overwrite/keep both) or open a per-item breakdown. Returns the
+/// `ConflictChoice` map `ServerProvider.resolveConflicts` expects, or null
+/// if dismissed without choosing.
