This commit addresses several security vulnerabilities in the authentication
and authorization system:
1. JWT Encoding Panic Fix (Critical)
- Replace .unwrap() with proper error handling in JWT token generation
- Prevents server crashes from encoding failures
- Returns HTTP 500 with error logging instead of panicking
2. Rate Limiting for Login Endpoint (Critical)
- Add actix-governor dependency (v0.5)
- Configure rate limiter: 2 requests/sec with burst of 5
- Protects against brute-force authentication attacks
3. Strengthen Password Requirements
- Minimum length increased from 6 to 12 characters
- Require uppercase, lowercase, numeric, and special characters
- Add comprehensive validation with clear error messages
4. Fix Token Parsing Vulnerability
- Replace unsafe split().last().unwrap_or() pattern
- Use strip_prefix() for proper Bearer token validation
- Return InvalidToken error for malformed Authorization headers
5. Improve Authentication Logging
- Sanitize error messages to avoid leaking user existence
- Change from "User not found or incorrect password" to "Failed login attempt"
All changes tested and verified with existing test suite (65/65 tests passing).

Leverage generics to remove the extra heap allocation for the response
handlers using Dao's. Also moved some of the environment variables to
app state to allow for easier testing.
