The M6 SPA shipped the create wizard but the detail page was read-only —
even though the backend already exposed PUT /missions/{id}, POST
/missions/{id}/scenarios, and PUT /missions/{id}/members. So once a
mission was created you couldn't fix a typo in the client name, add a
scenario you forgot, or change member assignments without curl.
Added three modals on the detail page, gated by `is_admin ||
mission.update`:
- Edit metadata (header button, 3xl modal): name + client + dates +
markdown description, same validation as the wizard step 1.
- Add scenarios (Tests tab): scenario picker matching wizard step 2,
calls POST /missions/{id}/scenarios which appends snapshots at
current_max_position + 1.
- Edit members (Members tab): roster + red/blue toggles, calls
PUT /missions/{id}/members (full-set replace), pre-populated with
the current member set.
The detail page now imports useAuth so `canEdit` is computed once and
shared between the three buttons.
E2E: new "detail page edits metadata, appends scenarios, edits members"
spec exercises the three modals end-to-end. M6 e2e count is now 6.
