feat: add partner interface, admin dashboard, and unit tests
Partner flow: QR scanner component (html5-qrcode) with camera permission/not-found handling, 3-step spend flow (scan → amount entry with auto-filled max → success/error result). Admin dashboard: stats overview, grant points with debounced student search, paginated transactions table with type filters, paginated students table. Tests: comprehensive unit tests for points and auth packages — service (all paths including error branches, RS256 wrong-method), handler (all HTTP status codes via httptest), JWT round-trip, repository constructors. Auth coverage: 72.9%, points service coverage: 100%. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
