fix(ci): use master Docker images for all PRs to support release branches

Docker images like `thirdparties-bin-test-ubuntu2204-v2.5` don't exist
for release branches, causing CI startup failures.

This change hardcodes all Docker image tags to use 'master' branch images,
ensuring CI works for all branches including v2.5 and other release branches.

Notes:
- Added comment explaining the rationale at the top of the file
- Updated image tags for: Tidy, IWYU, Build/Test Release, ASAN, jemalloc, Rockylinux9
- clang-tidy now compares against origin/master instead of origin/base_ref
