Replaced all inline error messages with the standardized `api_error` helper for consistent error response formatting. This improves clarity, maintainability, and ensures uniform error structures across the application. Updated logging for collector failures to include error class and switched to warning level for target unreachable scenarios.
Switched the dependency from `python-jose` to `PyJWT` to handle JWT encoding and decoding. Updated related code to use `PyJWT`'s `InvalidTokenError` instead of `JWTError`. Also bumped the application version from `0.1.7` to `0.1.8`.
