Depends on https://github.com/actualbudget/docs/pull/202.

- Enforce that imports from the same package are merged into a single
import
- In `loot-core`, require that imports of other `loot-core` files use a
relative import (like the vast majority of such imports) rather than
specifiers starting with `loot-core/` (probably a result of moving files
out of other packages into `loot-core`)

Seems to build fine, will test later.

This PR improves the consistency of the settings UI by moving everything
(except the budget name field on mobile) into `<Setting>` boxes.
Additionally, it adds a “Settings” option to the file dropdown menu (I
keep expecting it to be there, and I think it’s reasonable to expose it
in both locations so it’s easier to access)

Refactored all feature flags to use the new `useFeatureFlag` hook.

Also added a new functionality to this feature flag: ability to define
custom "default" value for a feature flag. This will allow us to enable
the new autocomplete component for everyone using Netlify builds
eventually (need to address some issues before doing so).
