Fix message routing bug and update Phase 10 status

- Fix messages route to use conversations-api handler (sub-action pattern)
  instead of messages-api (was creating separate resources instead of
  appending to conversation's messages array)
- Fix SPA chat.js to send 'body' field matching handler's field mapping
  (was sending 'content' which was ignored)
- Mark Phase 10 complete in ROADMAP (multi-affiliate routing, JWT claims,
  handleGetAll filtering, conversation router, SPA scoping all verified)
- Add Phase 11 plan for E2E QA & Polish
- Add QA screenshots documenting verified functionality

 ### Multi-Affiliate Conversation Routing
-- [ ] JWT claims enrichment with affiliateId/programIds from user metadata
-- [ ] handleGetAll() filtering by affiliate/program query params with JWT defaults
-- [ ] Conversation router with real routing logic (keyword → program → affiliate mapping)
-- [ ] Queue health scoping by affiliate (non-admin users see only their affiliate's data)

 ### Conversation Data Fixes

+- [ ] Login flow: verify all 8 seed users can log in with correct roles
+- [ ] Conversation routing: send messages with HELLO/TEEN/WELLNESS/PARTNER keywords, verify routing
+- [ ] Cross-affiliate isolation: login as aff-001 responder, verify only aff-001 conversations visible
+- [ ] Supervisor view: verify supervisors see only their affiliate's responders and conversations
+- [ ] Message flow: send messages both directions, verify real-time updates
+- [ ] Multi-chat: open multiple conversations simultaneously, verify messages route correctly
+- [ ] Queue health: verify per-affiliate program stats display correctly
+- [ ] Transfer flow: transfer conversation between responders, verify handoff
+- [ ] Escalation flow: test medical/police escalation state transitions
+- [ ] Screenshot documentation: capture key states for USER_GUIDE.md
