Feature: remember value of chart period selector (#1528)

* 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
