feat(gitlab): add repository, code-review, and CI job tools + validation fixes (#5205)

* feat(gitlab): add repository, code-review, and CI job tools + validation fixes

Expand the GitLab integration with 12 new tools (all host-aware via
getGitLabApiBase, wired through types/index/registry/block):
- Repository: list_repository_tree, get_file, create_file, update_file,
  create_branch, list_branches, list_commits
- Code review: get_merge_request_changes, approve_merge_request
- CI jobs: list_pipeline_jobs, get_job_log, play_job

Validation fixes from /validate-integration:
- Correct the block inputs key (credential -> accessToken) so it matches the
  subBlock id and the params the block reads
- Trim projectId before encoding in all tool request URLs (input hygiene)

/validate-connector and /validate-trigger passed clean against the GitLab REST
API v4 docs — no changes required.

* fix(gitlab): address review feedback + regen docs

- get_merge_request_changes: use the /diffs endpoint (/changes was removed in
  GitLab 18.0); return the diff array + count (drops the MR envelope that /diffs
  no longer provides), fetch max page size in a single call
- create_file/update_file: send explicit `encoding: 'text'` for clarity
- Remove `// =====` separator comments from types.ts (repo convention)
- Regenerate GitLab integration docs + catalog for the 12 new tools
