fix(domains): stop fill_form misreporting select-by-label, let it fail

Three review fixes on the restored fill_form:

- FILL_FN matches a <select> option by value, label or text but returns
  el.value, so filling by visible label ("Canada" -> value "ca") tripped
  the read-back mismatch check and reported a correctly-set field as
  "Filled 0/1 fields; issues: ref e4 (value mismatch)". The mismatch test
  now also accepts res.text, which FILL_FN sets only for selects, so
  mismatch detection is preserved for every other field kind.
- fill_form always returned ok(), so total failure surfaced as a
  successful result reading "Filled 0/4 fields". It now returns
  invalid_state when okCount is 0, carrying the per-field issue list as
  the error message. Partial success stays ok().
- Removed the two comment blocks this task had added to
  test/manual/forms-test.ts.

Neither behaviour fix has automated coverage; the manual suite that would
exercise them still needs a live Chrome and was not run.
