Use i18n for board component strings, show controls in edit mode, require website before editing

- Replace raw strings with useMessages hook in BoardColumn and BoardComponentSelect
- Show WebsiteControls on edit screen so users can test filters
- Disable board body editing until a website is selected
- Scope website select to team websites when editing a team board
