refactor: use localDateTimeToUtcIso in component and clean up tests
- Import and call localDateTimeToUtcIso in the add-game onSubmit handler
  instead of duplicating the conversion inline; also applies the null/
  invalid-date safety from the utility to the component
- Remove the redundant "incompatible with datetime-local" test case (its
  intent is better expressed as a code comment than a test assertion)
- Move the datetime-local incompatibility explanation into a NOTE comment
  on the utility function's JSDoc
