Replaces stub schedule CRUD with full shift template + instance system.

- DB: add shift_templates, shift_template_roles, shift_template_volunteers,
  shift_instances, shift_instance_volunteers tables
- schedule package: ShiftTemplate and ShiftInstance models with store
  (generate, publish/unpublish, per-instance edits, volunteer confirmation)
- API: shift-templates CRUD + shifts generate/publish/unpublish/update/confirm
- Notifications sent on publish (FR-S04), unpublish (FR-S05), instance edit
  (FR-S09), and volunteer added mid-month (FR-S10)
- Frontend: Schedules page with month navigation, template management,
  publish/unpublish controls, and per-shift edit/confirm
- Tests: Go handler tests (14 cases) + React tests (11 cases)
