d111eccf9a fix: Fix all identified bugs and add comprehensive tests
This commit fixes 5 critical bugs found during code review:

Bug #1 (CRITICAL): Missing API endpoints for election filtering
- Added GET /api/elections/upcoming endpoint
- Added GET /api/elections/completed endpoint
- Both properly filter elections by date

Bug #2 (HIGH): Auth context has_voted state inconsistency
- Backend schemas now include has_voted in LoginResponse and RegisterResponse
- Auth routes return actual has_voted value from database
- Frontend context uses server response instead of hardcoding false
- Frontend API client properly typed with has_voted field

Bug #3 (HIGH): Transaction safety in vote submission
- Simplified error handling in vote submission endpoints
- Now only calls mark_as_voted() once at the end
- Vote response includes voter_marked_voted flag to indicate success
- Ensures consistency even if blockchain submission fails

Bug #4 (MEDIUM): Vote status endpoint
- Verified endpoint already exists at GET /api/votes/status
- Tests confirm proper functionality

Bug #5 (MEDIUM): Response format inconsistency
- Previously fixed in commit e10a882
- Frontend now handles both array and wrapped object formats

Added comprehensive test coverage:
- 20+ backend API tests (tests/test_api_fixes.py)
- 6+ auth context tests (frontend/__tests__/auth-context.test.tsx)
- 8+ elections API tests (frontend/__tests__/elections-api.test.ts)
- 10+ vote submission tests (frontend/__tests__/vote-submission.test.ts)

All fixes ensure frontend and backend communicate consistently.

- Set dark mode as default theme
- Create ThemeToggle component with Sun/Moon icons
- Add theme toggle to home page navigation
- Add theme toggle to dashboard header
- App now starts in dark mode with ability to switch to light mode

Styling uses existing Tailwind dark mode variables configured in
tailwind.config.ts and globals.css. All existing components automatically
support dark theme.

9f5aee8b93 fix: Reorder election routes to fix blockchain endpoint routing
Moved specific routes (/blockchain, /debug/all, /active, /completed, /upcoming)
BEFORE generic routes (/{election_id}, /{election_id}/results, etc) so that
specific paths are matched first and don't get caught by the {election_id}
path parameter matcher.

Also removed duplicate /completed and /upcoming route definitions.

Routes now in correct order:
1. Specific paths: /debug/all, /active, /blockchain
2. Specific subpaths: /{id}/blockchain-verify, /{id}/candidates, /{id}/results
3. Generic: /{id}

1a42b4d83b feat: Implement blockchain-based election storage with cryptographic security
Elections are now immutably recorded to blockchain with:
- SHA-256 hash chain for integrity (prevents tampering)
- RSA-PSS signatures for authentication
- Candidate verification via SHA-256 hash
- Tamper detection on every verification
- Complete audit trail

Changes:
- backend/blockchain_elections.py: Core blockchain implementation (ElectionBlock, ElectionsBlockchain)
- backend/init_blockchain.py: Startup initialization to sync existing elections
- backend/services.py: ElectionService.create_election() with automatic blockchain recording
- backend/main.py: Added blockchain initialization on startup
- backend/routes/elections.py: Already had /api/elections/blockchain and /{id}/blockchain-verify endpoints
- test_blockchain_election.py: Comprehensive test suite for blockchain integration
- BLOCKCHAIN_ELECTION_INTEGRATION.md: Full technical documentation
- BLOCKCHAIN_QUICK_START.md: Quick reference guide
- BLOCKCHAIN_IMPLEMENTATION_SUMMARY.md: Implementation summary

API Endpoints:
- GET /api/elections/blockchain - Returns complete blockchain
- GET /api/elections/{id}/blockchain-verify - Verifies election integrity

Test:
  python3 test_blockchain_election.py
