fix: multiple twenty orm issues & show an example of use (#5439)

This PR is fixing some issues and adding enhancement in TwentyORM:

- [x] Composite fields in nested relations are not formatted properly
- [x] Passing operators like `Any` in `where` condition is breaking the
query
- [x] Ability to auto load workspace-entities based on a regex path

I've also introduced an example of use for `CalendarEventService`:
