security: Add author whitelist for task router (Issue #132)

Browse Source 
Implements security fix for issue #132 - Task router author whitelist

Changes:
- Add author_whitelist.py module with whitelist validation
- Integrate whitelist checks into task_router_daemon.py
- Add author_whitelist config option to config.yaml
- Add comprehensive tests for whitelist validation

Security features:
- Validates task authors against authorized whitelist
- Logs all authorization attempts (success and failure)
- Secure by default: empty whitelist denies all
- Configurable via environment variable or config file
- Prevents unauthorized command execution from untrusted Gitea users

Author Whitelist Module — Security Fix for Issue #132
Validates task authors against an authorized whitelist before processing.
Prevents unauthorized command execution from untrusted Gitea users.
Configuration (in order of precedence):
1. Environment variable: TIMMY_AUTHOR_WHITELIST (comma-separated)
2. Config file: security.author_whitelist (list)
3. Default: empty list (deny all - secure by default)
Security Events:
- All authorization failures are logged with full context
- Logs include: timestamp, author, issue, IP (if available), action taken
