feat: team module, multi-stage Dockerfile, doctor utils, AI config overhaul

- Team module: POST /api/team/members (in-place employee creation with
  temp password + Redis cache), PUT /api/team/members/:id, GET temp
  password endpoint. Uses signUpInWorkspace — no email invites.
- Dockerfile: rewritten as multi-stage build (builder + runtime) so
  native modules compile for target arch. Fixes darwin→linux crash.
- .dockerignore: exclude dist, node_modules, .env, .git, data/
- package-lock.json: regenerated against public npmjs.org (was
  pointing at localhost:4873 Verdaccio — broke docker builds)
- Doctor utils: shared DOCTOR_VISIT_SLOTS_FRAGMENT + normalizeDoctors
  helper for visit-slot-aware queries across 6 consumers
- AI config: full admin CRUD (GET/PUT/POST reset), workspace-scoped
  setup-state with workspace ID isolation, AI prompt defaults overhaul
- Agent config: camelCase field fix for SDK-synced workspaces
- Session service: workspace-scoped Redis key prefixing for setup state
- Recordings/supervisor/widget services: updated to use doctor-utils
  shared fragments instead of inline visitingHours queries
