Pre hook for dashboard creation + updates on the entity (#14354)

Closes https://github.com/twentyhq/core-team-issues/issues/1417

- The pre-hook creates a page-layout and links it to the dashboard
- Added `position`, `createdBy`, `attachments`, `searchVector`,
`favorites` to the dashboard entity
- Updated the view seed
- Updated the page layout services to work within a transaction
