feat(fusion_portal): wire ADP/express into visit + portal entry tile + email consolidation

- express save captures visit_id; when visit-linked, action=submit saves the
  ADP assessment as a draft (signature + Page 11 PDF still captured) and returns
  to the visit instead of completing into a standalone SO, so the visit groups
  the ADP devices into one funding-routed order. Non-visit express flow unchanged.
- portal dashboard: featured 'Start a Visit' tile (sales reps) -> /my/visit/new.
- fix duplicate-authorizer email: _send_completion_notifications no longer
  re-emails the authorizer (already emailed with the full report by
  _send_assessment_completed_email); it now only notifies the client.
- visit grouped accessibility SOs now send one office completion email per SO.

Bump 19.0.2.10.0.
