feat: add updatedBy field to track last record modifier (#16807)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Implements last-modifier tracking and unified actor injection.
> 
> - New `ActorFromAuthContextService` replaces createdBy-only logic;
pre-query hooks now inject both `createdBy` and `updatedBy` on create
and `updatedBy` on update
> - Add `updatedBy` standard field to core/custom objects (e.g.,
`person`, `company`, `task`, `note`, `attachment`, `dashboard`,
`workflow`, `workflowRun`) with IDs, metadata builders, and ORM entity
fields
> - Record CRUD: `create` now sets both `createdBy` and `updatedBy`;
`update` sets `updatedBy`; workflow actions use a shared workflow actor
builder; REST base handler uses the new actor service
> - Seeder data and snapshots updated to include `updatedBy`; GraphQL
result formatting adds defaults/handling for empty composite fields
(incl. actor)
> - Frontend `useUpdateOneRecord` upserts returned record into the local
store after mutation
