fix(pagespeed): make frequency interactive and show next check time

- Replace dead frequency badge with inline dropdown selector
- Add "Next in Xh" indicator from next_check_at
- Demote "Disable" button to subtle text link (was competing with Run Check)
- Add cursor-pointer to prev/next history arrows
- Narrow filmstrip fade to avoid covering content
