ci(e2e): workflow fixes and cleanups for SDS-only PR\n\n- top-level concurrency + unified job concurrency (head_ref||ref_name) to prevent duplicate runs\n- use DEV_REGISTRY_DOCKER_CFG only; inject into values; login via docker cfg\n- fix Actions 'if' expressions (no secrets.* in if; use env)\n- add Apache-2.0 headers to helper scripts (dmtlint)\n- format ci/dvp-e2e/Taskfile.yaml with repo Prettier (prettier)\n- trim push triggers to ci-e2e-nested-sds only; remove noisy comments
