• The fallback block in _validate_api_key is unreachable due to the exhaustive preceding conditions; refactor the logic to ensure clarity and remove dead code.

        # Otherwise, fall back to the original validation logic

Updated:

• auth enable/disable and custom secret can be set with mcpm router set --auth/--no-auth --secret [custom secret]
• if auth disabled for router, secret key check will be skipped
• share will use the configured auth secret rather than generate a different one every time
