Parship Chowdhury ba493e5a23 fix: show relation field changes in the timeline (#21052)
## Summary
- Fixes #20970 
- When we changed only a relation field (e.g. company on a person):
- The diff builder skipped all RELATION fields -> empty diff -> no
timeline row.
- If we change company and something else, only the scalar field
appeared; the company change was missing.
- Even with a diff, the UI validated keys by field name (`company`)
while join columns (`companyId`) could be filtered out.

## Solution
- For `MANY_TO_ONE`, compare join column values (`companyId`) and store
the diff under the relation field name (`company`):
```
"company": {
  "before": { "id": "<old-id>" },
  "after": { "id": "<new-id>" }
}
```
- Frontend
- `filterOutInvalidTimelineActivities`: resolve diff keys by field name
or join column via `findFieldMetadataItemByDiffKey`, so relation diffs
are not stripped.
- `EventRelationFieldDiffValues`: resolve related record labels by id;
show only the new value in the row (same pattern as other fields:
Company -> airSlate).
- Tooltip (relations only): on hover, show before -> after with readable
names (e.g. Microsoft -> Apple). Scalar and composite fields (e.g.
Updated by) are unchanged and do not get this tooltip.
- `EventFieldDiff`: route RELATION diffs to the relation renderer; all
other field types keep the existing FieldDisplay behavior.

### What you’ll see
On a person (or opportunity) timeline after changing company:
```
You updated Company → airSlate
(tooltip: Microsoft → Apple)
```

## Test plan
- Change only company on a person -> timeline shows a company update
with names.
- Change company and name in one save -> both appear in the diff.
- Clear company -> row shows Empty; tooltip reflects previous -> empty
if applicable.
- Same we can do for the Opportunities also
- Scalar / ACTOR fields (e.g. Updated by) - no new tooltip; display
unchanged.
