Stop the weather worker pinning location for providers that manage it

Breezy Weather resolves its own location and pushes weather updates, but
WeatherUpdateWorker only looked at autoLocation before requesting a location.
BreezyWeatherProvider.getWeatherData() is a noop that always returns null, so
the worker then returned Result.retry() forever and never set lastUpdate -
which meant the update interval check could never short-circuit it either.

Every attempt called getLastKnownLocation(), which registers GPS *and* network
listeners at a one second interval and held them for up to ten minutes, so the
location stack never idled. On the phone this showed up as ~46k delivered fixes,
`*location*` wakelocks held ~99% of the time and Doze never engaging at all.

- expose the selected provider's managedLocation in WeatherSettingsData
- skip and cancel the weather work for providers that manage their own location
- give up on a fix after two minutes instead of ten
- LocationsRepository: don't collect the location flow when location search is
  off or not permitted. As a combineTransform argument it was always collected,
  so every search query registered GPS and network listeners for up to 30s.

Bump to 1.40.2-typing.8 (versionCode 2026091201).
