fix(workflows): allow test/* branches to merge into dev

Updated pr-into-dev.yml to accept test/* branches:
- Added test to branch name validation regex
- Updated header documentation
- Added test/ to allowed patterns list

Branch patterns now allowed for PRs into dev:
- feature/* (new features)
- fix/* (bug fixes)
- hotfix/* (critical fixes)
- test/* (workflow testing)

This enables proper testing flow: test/* → dev → main
