chore: clean up stale TODO comments and update issue references

[pbeza]

Clean up stale TODOs referencing closed GitHub issues and update references where work moved to new issues.

Split from the CI check work — the script and workflow changes are in #2749. This PR focuses on the TODO comment cleanup.

Closes #2750

Code Review

Clean housekeeping PR. The new check-todo-closed-issues.sh script is well-structured: it batches GitHub API calls into a single GraphQL query, handles errors gracefully, and runs as non-blocking in CI (continue-on-error: true). The stale TODO removals look correct — context was preserved where needed (e.g., the migration-service doc now links to an existing backup-service-attestation-data.md), and the re-tagged TODO(#2102) in run.rs correctly points to an open issue.

No blocking issues found.

Pull request overview

Adds a new CI-side audit to detect TODO(#NNN) comments that reference already-closed GitHub issues, and cleans up/updates a set of stale TODOs across the repo to reduce misleading technical-debt markers.

Changes:

• Add scripts/check-todo-closed-issues.sh to query GitHub and fail on TODOs pointing to closed issues (intended as a non-blocking CI warning).
• Wire the check into CI (non-blocking) and expose it locally via cargo make todo-closed-issues.
• Remove/update multiple stale TODOs (and a few related formatting-only tweaks) across Rust, docs, config, and workflow files.

• In CI this step will likely run unauthenticated: gh api graphql requires a token (typically via GH_TOKEN/GITHUB_TOKEN env). Consider setting GH_TOKEN: ${{ github.token }} for this step (or job-wide) and updating fast-ci-checks job permissions to include issues: read, otherwise the check may consistently fail and show a permanent yellow warning.

This check is not part of check-all-fast because it can't be a blocking check — someone closing an issue as "not planned" would suddenly break CI on unrelated PRs. It also requires GitHub API access (gh authenticated), unlike other fast checks.

Code Review

Clean housekeeping PR. No critical issues found.

Minor (non-blocking): In check-todo-closed-issues.sh line 62, the grep pattern uses unescaped parentheses which are regex metacharacters. Consider grep -Fn for exact fixed-string matching. Not blocking since false positives are extremely unlikely.

PR title type suggestion: This PR primarily adds new CI infrastructure (workflow and check scripts), so the type prefix should probably be ci: instead of chore:.

Suggested title: ci: add check for TODOs referencing closed issues and clean up stale TODOs
