Sea Select options: fixed-width chunks + 2-line spread names (add Rider-) — TDD

- The option chunks' width tracked the select label length (jumped between the
  two spreads). Fix the `.sea-form-col` to 19rem (a touch wider) so all three
  chunks share a standard width.
- Split the spread label onto two lines around the comma + add the "Rider-"
  prefix now there's room: "Celtic Cross," / "Rider-Waite-Smith" and "Celtic
  Cross," / "Escape Velocity". combobox.js now writes the current label via
  `innerHTML` (not textContent) so the `<br>` survives a selection — plain-text
  options (sky / my_sea) are unaffected (their innerHTML == textContent).
- ITs updated for the new gameroom labels (my_sea's single-line names untouched).
