* feat: remember chart period by last selection not user preferences
* feat: schema update
* fix: revert unnecessary parts of schema.rb update
* fix: check period key is valid before setting it
* revert: no database changes and keep the UI setting
* refactor: don't store the default period in the session, just use the user
* fix: migration
The migration uses the User model directly, which loads all current enums
including ui_layout which doesn't exist yet at that point in migration history.
Fix it with raw SQL.
* revert: not relevant to this PR
