fix: unify RELEASE variable for check_for_gh_release and fetch_and_deploy_gh_release

- Simplify pinned version check: query exact tag directly instead of candidate loop
- Use same RELEASE variable in both check and deploy calls
- immich: use RELEASE='v2.5.6' consistently (remove RELEASE_TAG indirection)
- nocodb/patchmon/plant-it: extract shared RELEASE variable for both functions
