Enhance timeout_start_sec_for_domains filter to accept dict, list, or str

- Updated filter to handle dict (domain map), list (flattened domains), or single str inputs.
- Prevents duplicate 'www.' prefixes by checking prefix before adding.
- Adjusted unit tests:
  * Replaced old non-dict test with invalid type tests (int, None).
  * Added explicit tests for list and string input types.
