fix: resolve features-store test timeouts and dynamic icon-map test (#151)

- Fix installAll tests timing out by returning installed status from
  refreshBundles mock (prevents infinite retry loop) and increasing
  waitFor/test timeouts to accommodate the 2s inter-install delay
- Fix zustand-stores installAll test with same refreshBundles mock fix
- Icon-map test already fixed to derive from shared constants
