Allow custom fields to be editable for system objects and prevent the error for timeline activity on system object pages. (#16268)

Solves #16015 

- Added a check in `useTimelineActivities.ts` to see if the system
object page we're viewing has timelineActivity being tracked before
querying to get the activity history.
- Removed @WorkspaceIsObjectUIReadOnly decorator from system objects and
added @WorkspaceIsFieldUIReadOnly to standard and system fields to allow
custom field edits as requested in the issue.
- Did not add calendarEvents or other system objects to timelineActivity
just yet since keeping track of timeline activity for every one of them
felt counter-intuitive and bloated. In order to determine which objects
need timelineActivity, I think we need to fix the broken views of system
objects first, such as the one in the attached screenshots - a good
number of them are broken. The check I added to
`useTimelineActivities.ts` hook displays timeline activity as empty for
the time - error would not be shown as suggested by Thomas.

- Editing custom fields on calendar events (and other objects without
position fields) crashed with TypeError: Cannot convert undefined or
null to object in sortCachedObjectEdges. This happened because some
cached queries had empty orderBy arrays ([]), and the optimistic effect
tried to sort with them. Objects without position fields returned
empty orderBy arrays when there were no sorts, while objects with
position fields automatically got [{ position: 'AscNullsFirst' }].
The backend always adds { id: 'AscNullsFirst' } as a fallback, but
the frontend didn't match this. So, I added { id: 'AscNullsFirst' } to
the Frontend as default orderBy when there are no sorts and no position
field.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Apply per-field UI read-only to system/standard fields and skip
timeline activity fetching when the target object isn’t related; refine
record-table cell open/navigation behavior.
> 
> - Server: Replace object-level UI read-only with per-field
`isUIReadOnly` across many standard objects (e.g., `calendarEvent`,
`workspaceMember`, messaging, calendar, favorites, attachments,
workflows, etc.), and mirror this via `@WorkspaceIsFieldUIReadOnly` on
workspace entities.
> - Frontend: In `useTimelineActivities.ts`, check object metadata for a
relation to `timelineActivity` and `skip` the query when absent,
preventing errors on system object pages.
> - Frontend: Simplify/adjust record-table cell logic—remove unused
args, allow navigation from first column when non-empty, block editing
for read-only records (while still allowing navigation), and update
button handlers/hover styles accordingly.
