* feat: add toggle to opt out of booking title translation in instant meetings

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* fix: add autoTranslateTitleEnabled to test builder

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* fix: respect autoTranslateTitleEnabled toggle in InstantBookingCreateService

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* fix: fetch autoTranslateTitleEnabled directly in InstantBookingCreateService

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* refactor: rename autoTranslateTitleEnabled to autoTranslateInstantMeetingTitleEnabled

- Renamed field to clarify it only applies to instant meeting title translation
- Moved Prisma query to EventTypeRepository.findInstantMeetingConfigById()
- Removed title translation logic from update.handler.ts (flag only controls instant meeting title)
- Updated all references across the codebase
- Added new i18n translation keys for the renamed field

* fix: add autoTranslateInstantMeetingTitleEnabled to test destructuring patterns

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* fix: use Prisma.TeamCreateInput type for metadata in test helper

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* fix: add autoTranslateInstantMeetingTitleEnabled to mockUpdatedEventType in test

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* refactor: use generic findByIdMinimal instead of business-specific method

- Add autoTranslateInstantMeetingTitleEnabled to eventTypeSelect constant
- Remove findInstantMeetingConfigById from EventTypeRepository
- Update InstantBookingCreateService to use findByIdMinimal

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* refactor: remove autoTranslateInstantMeetingTitleEnabled from eventTypeSelect (not needed for findByIdMinimal)

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* feat: add autoTranslateInstantMeetingTitleEnabled to event type form defaults

- Rename shouldTranslateTitle to shouldAutoTranslateInstantMeetingTitle for clarity
- Add autoTranslateInstantMeetingTitleEnabled to findById and findByIdForOrgAdmin selects
- Add autoTranslateInstantMeetingTitleEnabled to useEventTypeForm defaultValues

Co-Authored-By: joe@cal.com <j.auyeung419@gmail.com>

* fix: only update autoTranslateInstantMeetingTitleEnabled when explicitly provided

Fixes issue where omitting the field in update requests would overwrite
the saved opt-out setting with the default value (true). Now the field
is only included in the update payload when explicitly provided.
