## Summary
- Move email thread display from side panel to a dedicated record page
with a new `EMAIL_THREAD` widget type
- Add message thread as a standard object with page layout, subject
field, and backfill command
- Add reply-to-email command menu item for message thread records
- Remove old side panel message thread components in favor of the new
widget-based approach
## Type fixes
- Add `EMAIL_THREAD` to `WidgetConfigurationType`, `WidgetType`, and all
configuration/validator maps
- Create `EmailThreadConfigurationDTO` and shared
`EmailThreadConfiguration` type
- Register EMAIL_THREAD in widget type validators, configuration
resolvers, and standard widget mappings
## Test plan
- [ ] Verify message thread record pages render with the email thread
widget
- [ ] Verify email thread preview navigates to the record page instead
of opening side panel
- [ ] Verify reply-to-email command appears for message thread records
- [ ] Verify typecheck passes for both twenty-front and twenty-server
- [ ] Run existing test suites to check for regressions

- Remove the label identifier field for all standard objects as it's a
first-class citizen that is displayed specifically in the app; it
doesn't make a lot of sense to display it in the Fields widgets
- Disable logic that made the label identifier required and in first
position
- Add all fields for all standard objects in record page layout view
fields
- Do not include position and ts vector fields in custom objects
> [!IMPORTANT]
> The command will create Field widgets for all relations. It is
consistent to the way the frontend dynamically generates them as of
today. We will have to decide which relations we pin as individual Field
widgets before the release. (This will likely land in this command or in
another one.)
