fix(workflows): run details-check on PRs and normalize ref resolution

Details Check was not running for PR #4903 because the workflow only
triggered on push to develop/workflow_dispatch. Also, pull_request refs
(refs/pull/*) are not valid raw-content refs for GitHub downloads.

Changes:
- Trigger Details Check on pull_request to develop
- Add LGSM_REF env resolved to PR head SHA or branch ref name
- Use LGSM_REF for linuxgsm.sh download and LGSM_GITHUBBRANCH usage
- Use LGSM_REF in matrix generation when fetching serverlist.csv

This ensures legacy server jobs (bfv, bf1942, btl, onset) are included
and executed during PR validation.
