New Timeline (#4936)

Refactored the code to introduce two different concepts:
- AuditLogs (immutable, raw data)
- TimelineActivities (user-friendly, transformed data)

Still some work needed:
- Add message, files, calendar events to timeline (~2 hours if done
naively)
- Refactor repository to try to abstract concept when we can (tbd, wait
for Twenty ORM)
- Introduce ability to display child timelines on parent timeline with
filtering (~2 days)
- Improve UI: add links to open note/task, improve diff display, etc
(half a day)
- Decide the path forward for Task vs Notes: either introduce a new
field type "Record Type" and start going into that direction ; or split
in two objects?
- Trigger updates when a field is changed (will be solved by real-time /
websockets: 2 weeks)
- Integrate behavioral events (1 day for POC, 1 week for
clean/documented)
