Subject: Add a 5am morning-fetch alarm so articles are fresh before you open
 the app

FeedFetchWorker's periodic 60-minute WorkManager job can (and does)
get silently deferred for hours by Doze on an idle overnight device.
An exact alarm (setExactAndAllowWhileIdle) wakes the device at a fixed
5am to run a fetch, without requesting the much broader "ignore
battery optimizations" exemption -- battery optimization stays on
otherwise, just this one daily wake-up.

Android 12+ requires a one-time user grant for exact alarms (no in-app
permission dialog); MainActivity requests it via Settings if not
already granted, tracked across rotation via savedInstanceState so a
config change doesn't re-trigger the Settings screen. The alarm also
gets re-armed on BOOT_COMPLETED, since AlarmManager alarms don't
survive a device restart on their own.
