Update website to read stats from new distribution

[lenaunderwood22]

Update source of certificate daily stats, which is now cert-daily-stats.tsv from a different distribution URL. Other artifacts are still retrieved from the old distribution URL.

New TSV file has the same columns in the same order as old TSV file. Only difference is the new TSV file has headers, which will get safely skipped.

Pull request overview

Updates the website’s certificate daily statistics graph to load data from a new distribution location/file (cert-daily-stats.tsv), while keeping other graph artifacts on the existing distribution URL.

Changes:

• Switch stats fetch from cert-timeline.tsv to cert-daily-stats.tsv and introduce a separate base URL for that file.
• Add a header row to the locally checked-in cert-daily-stats.tsv fixture/sample file.
• Update CSP connect-src allowlist to permit fetching stats from the new CloudFront distribution.
