## What does this PR do?
This PR adds user UUID plumbing from API v2 controllers through to packages/features functions. This is preparatory work extracted from PR #25125 to support future audit logging functionality.
**Key changes:**
- API v2 controllers (2024-04-15, 2024-08-13) now extract and pass `userUuid` to downstream functions
- `handleMarkNoShow` and `CancelBookingInput` types now accept optional `userUuid` parameter
- `UserRepository.findUnlockedUserForSession` now selects `uuid` field
- Session middleware now includes `uuid` in the returned user object
- Fixed lint warning: changed `PromiseSettledResult<any>` to `PromiseSettledResult<unknown>`
**Refactoring (optimization):**
- Renamed `getOwnerId` → `getOwner` and `getOwnerIdRescheduledBooking` → `getOwnerRescheduledBooking`
- These methods now return `{ id: number; uuid: string } | null` instead of just `number | undefined`
- This eliminates redundant database calls by fetching user id and uuid in a single query
**Important:** This is plumbing-only - packages/features receives the `userUuid` but does not use it directly (note the `_userUuid` prefix). The actual audit logging usage will come in a follow-up PR.

## Mandatory Tasks (DO NOT REMOVE)
- [x] I have self-reviewed the code (A decent size PR without self-review might be rejected).
- [x] I have updated the developer docs in /docs if this PR makes changes that would require a [documentation change](https://cal.com/docs). N/A - no documentation changes needed.
- [x] I confirm automated tests are in place that prove my fix is effective or that my feature works. N/A - plumbing only, existing tests cover the functionality.
## How should this be tested?
1. Run type checks: `yarn type-check:ci --force`
2. Verify the changes compile without new type errors related to uuid
3. The `userUuid` parameters are optional, so existing functionality should work unchanged
## Checklist
- [x] My code follows the style guidelines of this project
- [x] I have checked if my changes generate no new warnings
## Human Review Checklist
- [ ] Verify the `userUuid` parameter is intentionally unused (prefixed with `_userUuid`) - this is plumbing for future audit logging
- [ ] Verify all callers of `getOwner` and `getOwnerRescheduledBooking` correctly handle the new `{ id, uuid } | null` return type
- [ ] Confirm the change from `undefined` to `null` as the "not found" return value is handled consistently
- [ ] Verify the `uuid` field exists in the User model schema
