Done : 
- Fix getCalendarEventsFromPersonIds and getCalendarEventsFromCompanyId
(include accountOwner check)
- Fix permission check on pre-hook - Pre-hook seems useless, calendar
events are always on METADATA or SHARE_EVERYTHING visibility, else post
hook always has the responsibility of returning the data user can
access. >> To delete or to keep in case other visibility options are
added ?
- Add post hook to secure finOne / findMany calendarEvents resolver
- Update design

To do :
- same on messages (PR to arrive)
