refactor: reorganize to standard PHP structure
- Moved /lib → /src (PHP source code)
- Moved /includes → /public/includes (main site templates)
- Admin section remains self-contained in /public/admin with its own /inc
- Updated all require/include paths across codebase
- Updated config/bootstrap.php, justfile, tests, docs
- All tests passing ✅
Structure now follows PHP best practices:
/config - Configuration files
/database - SQLite database + schema
/docs - Documentation (intact)
/nginx - Server config (intact)
/public - Web-accessible files (entry point)
/admin - Self-contained admin interface
/assets - CSS, fonts, icons
/includes - Main site templates (header/footer)
/scripts - Deployment scripts (intact)
/src - PHP source classes (Database, AdminAuth, RateLimit)
/tests - Test suites
