Missing battery optimisation during onboarding.

[Soulthym]

During the first on-boarding, the app first asks the user to lift Android's background restriction, but does not ask to disable battery optimization.

We already have a setting under Notifications > Background Sync > Battery optimization which lets users fix it after the fact.

The goal here would be to perform both setting tweaks (lifting background restriction and disabling battery optimization) instead of just lifting background restriction during the initial on-boarding.

This should help in some cases where users did not receive notifications reliably, though it is worth noting that it might not be enough in all cases for all OSes depending on how aggressive they are with battery saving and killing background processes.

I checked the code and there is nothing related to battery or background restriction in the onboarding flow.
The only permission asked is to allow Notifications.
