V4: add WAITING_FOR_FILE_REVIEWER claim status; fix select-outer-parts for split flow

- Add ClaimCaseStatus.WAITING_FOR_FILE_REVIEWER (V4 split flow only)
- Set claim status to WAITING_FOR_FILE_REVIEWER when FileMaker uploads
  the last required document (v3InPersonFlow path), replacing the old
  behaviour that incorrectly auto-advanced to SELECT_OUTER_PARTS
- advanceV3ClaimToOuterPartsIfReady: also allow canAdvance when
  claimCase.status === WAITING_FOR_FILE_REVIEWER so the FileReviewer
  can call select-outer-parts after submitting accident fields
- Add WAITING_FOR_FILE_REVIEWER to CLAIM_USER_PHASE (unified-file-status)
  so the file still resolves to IN_PROGRESS in the unified status report
- Add WAITING_FOR_FILE_REVIEWER to CLAIM_IN_PROGRESS_STATUSES
  (expert-panel-status-report) for the expert report bucket
- Add WAITING_FOR_FILE_REVIEWER to claimInHandling set
  (expert-insurer.service) so insurer stats count these correctly
