careers: show apply email as plain text, drop mailto jumps (#5758)

The /careers/ page turned the apply address and every CTA into mailto:
links (hero button, the email itself, each role card, the closing button).
Clicking them yanked the visitor into their mail client, which felt abrupt.

Make the apply email a display-only element instead:
- hero + closing: render join@open-design.ai as a plain <span> (user-select:
  all so one click selects the whole address to copy), no mailto
- role cards: <a mailto> → non-clickable <div>; drop the "Apply →" affordance
  and the interactive hover lift
- enlarge the email (clamp(20px,2.6vw,26px), 700) so it reads as the CTA
- remove the now-dead copy fields (applyCta / applySubjectPrefix / roleApply)
  from the interface and all 12 locales

astro check passes (0 errors/warnings); /careers/, /zh/careers/, /ja/careers/
render with zero mailto links.
