feat(fusion_portal): ADP/express->visit wiring, visit entry tile, email consolidation (live on westin 19.0.2.10.0)

- express save captures visit_id; visit-linked submit defers SO creation
  (saves draft + signature) and returns to the visit for grouping.
- portal dashboard 'Start a Visit' tile for sales reps.
- fix duplicate-authorizer completion email; visit grouped SOs email once per SO.
- define visit._assessment_sale_type (ADP grouping key) - fixes AttributeError.

Verified on a westin-v19 clone (load + ADP-grouping + combination-guard smoke
test, mail neutralised) then deployed to westin prod 19.0.2.10.0.
