rCOMM85789c85773e: [lib] Fix SQLite migrations

Summary

The migrations are broken because we weren't using the right shape of the specification. This diff fixes it and introduces necessary type checks.

https://linear.app/comm/issue/ENG-9467/redux-migrations-are-broken

Test Plan

Tested this by creating a new migration on the web where a new draft is created. Run the app, and reopened it. Checked if the SET_CLIENT_DB_STORE action contains the draft.

1371 ↗	(On Diff #44820)	Even adding this check doesn't force Flow to verify the migrations' types so we have to explicitly annotate each migration.

Fix the import

lib/utils/migration-utils.js
207 ↗	(On Diff #44821)	I would name this `MigrationFunction`
210 ↗	(On Diff #44821)	Why remove `PersistedState` here?

lib/utils/migration-utils.js
210 ↗	(On Diff #44821)	`PersistedState` is an optional `AppState`. We were telling here that it can be used as an argument, but our migration functions were assuming that the `state` is mandatory. This issue was discovered by making the migration types explicit.
