QVAC-18543 fix: stabilize sdk e2e reports

[lauripiisang]

Note: be concise and prefer bullet points.

🎯 What problem does this PR solve?

• SDK e2e PR comments linked to artifact pages that took reviewers nowhere useful.
• Mobile test results were tied to Device Farm cleanup timing, delaying useful feedback.
• SDK e2e run IDs could collide across concurrent runs.
• Repeated identical failures made PR comments hard to scan.

📝 How does it solve it?

• Links PR comments directly to meaningful artifacts only: reports and mobile Device Farm logs.
• Publishes the first result comment when producer results are ready, then refreshes it after mobile logs upload.
• Generates run IDs from platform, PR number, commit SHA, and GitHub Actions job ID.
• Collapses repeated identical failures after five occurrences.

🧪 How was it tested?

• Ran git diff --check.
• Ran node --check on edited GitHub Script snippets.
• Verified job ID matching against a real SDK e2e run.
• Ran actionlint; it still reports existing unrelated workflow issues.
