Add specific icons for each repository resource type

- repository_content: repo icon
- repository_content_branch: git-branch icon
- repository_content_commit: git-commit icon (new)
- repository_content_tag: tag icon
- repository_content_pr: git-pull-request icon

Resources now have explicit icons set rather than relying on toolset fallback.
