security: apply 7 fixes from ZeroTrustino audit (#3)

1. SQL Injection Prevention - Parameterized queries on user input
2. XSS Vulnerabilities - HTML entity encoding in output rendering
3. CSRF Token Implementation - Added token validation on state-changing operations
4. Password Hashing - Upgraded to bcrypt with stronger salt rounds
5. Authentication Session - Implemented secure session tokens with expiration
6. API Rate Limiting - Added rate limit middleware to prevent brute force attacks
7. Dependency Audit - Updated vulnerable package versions and patched known CVEs
