Restructure repository and implement secure search feature
Phase 1: Consolidate shared infrastructure - Create shared/ directory for common code - Consolidate Database.php from front-backend and formulaire into unified shared/Database.php - Smart path detection for test.db vs posterg.db - Secure search with wildcard escaping and input validation - Support both singleton and direct instantiation patterns - Full CRUD methods for admin functionality - Move RateLimit.php to shared/ (30 requests/min) - Update all require paths across apps to use shared/ Phase 2: Reorganize directory structure - Rename front-backend/ → apps/public/ - Rename formulaire/ → apps/admin/ - Rename db/ → database/ - Update all file paths for new structure - Create root .gitignore excluding databases, cache, logs Implement secure search feature - Add apps/public/search.php with full-text search across theses - Search filters: query, year, orientation, AP program, keywords - Security features: - SQL injection prevention (prepared statements) - Wildcard injection prevention (escape % and _) - Input validation (max 200 chars, year range 1900-2100) - Rate limiting (30 req/min per IP) - Pagination limited to 100 results/page - XSS protection (htmlspecialchars on output) Add comprehensive test suite - Create apps/public/tests/ with proper structure - tests/Integration/SearchTest.php - 12 search scenarios - tests/Security/SecurityTest.php - vulnerability testing - tests/Unit/RateLimitTest.php - rate limit behavior - Create database/fixtures/CreateTestDatabase.php - Add apps/public/run-tests.php test runner - All tests passing (4/4 suites) Update deployment configuration - Rename justfile 'sync' recipe to 'deploy' - Create deploy group with separate deploy-public and deploy-admin - Add test-deploy recipe for test database - Exclude *.db, tests/, cache/, *.md from production deploy - Deploy shared/ to both public and admin locations Stats: +4482 insertions, -654 deletions across 72 files
