feat(validation): add branch name validation across provider schemas

- Introduced a regex validation for branch names in Bitbucket, Git, Gitea, GitHub, and GitLab provider schemas to ensure valid branch formats.
- Updated the corresponding schemas to include the new validation rule, enhancing input integrity and preventing potential errors.
- Added a utility for branch validation in the server utils.
