feat(code-review): add review analytics

[alex-alecu]

Summary

• Adds optional Code Reviewer analytics for personal and organization accounts.
• Saves structured change and finding totals when a review finishes, while keeping retries and repeat callbacks safe.
• Adds filters, coverage details, repository tables, and a GitHub organization contributor view.

Verification

1. Open Code Reviewer settings for GitHub or GitLab and select the Analytics tab.
2. Turn on analytics collection, complete a new review, and confirm its totals appear for the matching date and repository.
3. Turn collection off and confirm saved analytics stay visible while new reviews are not added.
4. For a GitHub organization, confirm members can view the dashboard but only owners and billing managers can change collection.

Visual Changes

N/A - local app services were not running for screenshots.

Reviewer Notes

• Collection is off by default and does not fill in old reviews.
• Contributor rankings are limited to GitHub organizations because GitLab does not provide a stable author identity here.
