ci(CAR-1373): apply dev's deploy-job restoration to uat (resolve 3-way)

The dev→uat 3-way merge of ci.yml conflicts on:
- CalVer logic (dev is the multi-line readable form)
- ref: main vs parameterized expression (dev wins, per CAR-1374)
- PR body base/head: dev wins (per CAR-1371 + acceptance criteria)
- CAR-1216 comment: dev added, uat didn't have it

Resolution: take dev's version of ci.yml (the corrected form per CAR-1373).
