fix(auto-upload): start auto upload right after resuming global upload pause

[ToteMeiSter]

Problem

Refs #17576

Since #17632 the global pause on the uploads screen also stops auto upload: AutoUploadWorker checks the pause before it starts and before each file. When the pause is lifted, UploadListMenuProvider.toggleGlobalPause restarts only FileUploadWorker. AutoUploadWorker is not started again, so the synced folders stay idle until the next trigger, usually the periodic AutoUploadRescanWorker. No file is lost, but the upload can wait for the whole period.

Change

When the pause is lifted, toggleGlobalPause calls FilesSyncHelper.startAutoUploadForEnabledSyncedFolders(syncedFolderProvider, backgroundJobManager, overridePowerSaving = false). UploadListFragment passes SyncedFolderProvider and BackgroundJobManager to the menu provider.

Notes

• startAutoUploadForEnabledSyncedFoldersIfNotActive is not used: it calls isAutoUploadScheduled, which blocks on WorkManager's ListenableFuture.get(), and this code runs on the main thread from a menu click.
• With overridePowerSaving = false the work is enqueued with ExistingWorkPolicy.KEEP. A worker that is running or enqueued is left alone, no upload is cancelled. A worker that stopped because of the pause has finished, so a new one is enqueued.
• The fix relies on the pause checks from fix(upload): pause #17632.
• UploadListMenuProvider gets a () -> FileUploadHelper provider (default FileUploadHelper.instance()), because FileUploadHelper.instance() needs MainApp.getAppComponent() and cannot be called in a unit test.
• Touches only UploadListFragment, UploadListMenuProvider and its test. No file overlap with the other three PRs (fix(auto-upload): restart folder runs that stay enqueued on rescan #17805, fix(sharing): download file before "Send copy to" #17807, fix(share): send original file instead of cached thumbnail #17808); trial merge of all four is clean.

How to test

• Unit: UploadListMenuProviderTest (resuming global pause starts auto upload of enabled folders without waiting for the rescan) fails without the change (WantedButNotInvoked), passes with it.
• Device: Checked on a HUAWEI Mate X7 (DEL-LX9, EMUI 15.0.0, Android 12) with a test build: works, auto upload starts right after the global pause is lifted.
