Akiba So 8ad7e086bb feat: Phase 3 — 视角/perspective presets + URL-driven granularity + doctor privacy ...

Phase 3 of the UX modernization. Frontend-only role view-presets (D2 — no
backend, no JWT role claim, honestly labeled 视角 not 权限). Three conflict-free lanes.

Role infrastructure (worker-session):
- sessionStore with single swappable getRoleSource() seam (localStorage today,
  one-line swap to /api/auth/me for future RBAC); Role = official|community|doctor|admin
- 视角 switcher in TopNav (replaces hardcoded "admin"); on change persists role +
  navigates to that perspective's default landing
- roleViews.ts: ROLE_LABELS + roleDefaultPath (official→/overview?granularity=district,
  community→/monitoring?granularity=street, doctor→/alerts?view=cluster, admin→/monitoring)
- RoleRedirect index route → current role's default; * fallback unchanged

URL-driven granularity (worker-monitoring):
- granularity (city|district|street) query param is the source of truth; drilldownStore
  DERIVES from it via a one-way effect; deep-linkable + reload-safe
- reconciled the imperative desync — DistrictBreakdown no longer calls
  useDrilldownStore.getState(); MonitoringDashboard owns useSearchParams, writes URL
- granularity-control Segmented (全市/区域/街道); district-rollup testid

Role-aware alerts + privacy (worker-alerts):
- doctor/cluster view: individual alert markers hard-locked off (effective flag is
  single source of truth; toggle not rendered) → aggregated density only; DiseaseFilter
  mounted; privacy invariant testable via hidden patient-point DOM mirror (count=0)
- 官员: 100m grid hidden (grid-layer-wrapper unrendered); admin/community unchanged
