Reference site keeps the page fully visible while the checkin modal
is open; make the shell overlay transparent (still closes on click
outside) and rebuild public bundles.
- Rebuild checkin details modal HTML 1:1 with reference theme:
colorful header c-blue, user card (points/level), daily reward
card and 7-day continuous mini cards
- Signed entry buttons (header dropdown, user-card badge, user
center) become clickable checkin-details-link modal triggers
instead of disabled buttons
- Swap data-signin-btn to details link in place after successful
signin (reference .initiate-checkin replacement behavior)
- Add aksrt-checkin-details-modal runtime shell (modal-mini 400px)
- Remove dead code: legacy lite modal, admin-ajax details handler,
/signin/history route, signin calendar; rebuild public bundles
- Update contract tests to the new checkin modal contract
