fix(ci): resolve mypy and check_code_and_doc_quality CI failures (#21812)

- fix(mypy): suppress [misc] type error in common_utils.py for cls.__init__ access
- fix(mypy): move type: ignore comment to correct line in test_eval.py (line 232 not 231)
- fix(mypy): suppress [misc] and pre-existing pyright errors in vertex_ai_non_gemini.py
- fix(check_licenses): strip inline comments before parsing requirements.txt lines so CVE comments don't break packaging.requirements.Requirement()
- fix(router_coverage): add _merge_tools_from_deployment and _invalidate_access_groups_cache to ignored list (private helpers tested indirectly)
