fix(code-review): log repo size

[alex-alecu]

Summary

This adds a safe size check before a cloud code review starts. When the review session is ready, the logs now show the review id, both session ids, and the repo size if the provider gave one. If the size check fails, the review still starts and logs null. Retry attempts keep the same size value so later logs can be matched.

Verification

N/A - this is a backend log-only change with no screen to click through.

Reviewer Notes

The size is the value GitHub or GitLab reports for stored repo data. It is not the exact amount cloned over the network.

Executive Summary

The incremental changes since the last review (commits 66623fd and 713679f) cleanly inline the lookupRepositorySize helper into both the GitHub and GitLab branches and update tests accordingly — no regressions or new issues introduced.
