QVAC-17801 feat: add mobile Parakeet RTF reporting

[ogad-tether]

🎯 What problem does this PR solve?

• Parakeet performance reporting needed a mobile Device Farm path that uses the shared QVAC perf-report pipeline.
• The earlier branch-local mobile RTF extractor was brittle and did not match the working mobile workflow pattern.
• Desktop and mobile performance data should be visible together in CI artifacts so cross-platform regressions are easier to review.

📝 How does it solve it?

• Wires Parakeet mobile tests into scripts/test-utils/performance-reporter.js.
• Emits [PERF_REPORT_START] / [PERF_CHUNK] markers from mobile Device Farm logs and extracts them with scripts/perf-report/extract-from-log.js.
• Renders mobile summaries with scripts/perf-report/render-step-summary.js.
• Extends scripts/perf-report/aggregate-parakeet-rtf.js so the unified Parakeet report can include desktop RTF artifacts and mobile performance-report.json artifacts.
• Adds a unified report job that uploads parakeet-unified-performance-report.{md,json,html}.
• Keeps Android on the broader mobile model coverage, and quarantines only iOS Sortformer GPU after Device Farm showed that case backgrounds/crashes the app.
• Addresses PR bot findings by exporting generated mobile wrappers and checking out trusted workflow code in the privileged pull_request_target combine job.
