fix: Configure ffprobe path + bump ffprobe dep

[jennifer-shehane]

Additional details

In looking at how this package was being used, it seemed to be missing the path setup. The ffprobe path is now set when video_capture.ts loads, ensuring it's configured for all video operations, not just in tests.

• Upgrades @ffprobe-installer/ffprobe from 1.1.0 to 2.1.2 to support darwin-arm64 (Apple Silicon).
• Moved ffprobe path setup so it's configured at module load time
• Removed redundant ffprobe setup from system-tests/test/video_compression_spec.js

---

Note

Configures ffprobe globally for video operations, upgrades @ffprobe-installer/ffprobe to 2.1.2, removes redundant test setup, and updates changelog.

• Server (video capture):
  • Set ffprobe path at module load in packages/server/lib/video_capture.ts via ffmpeg.setFfprobePath(ffprobePath).
  • Upgrade @ffprobe-installer/ffprobe to 2.1.2 and move to runtime dependencies in packages/server/package.json.
• Tests:
  • Remove redundant ffprobe path configuration from system-tests/test/video_compression_spec.js.
• Docs/Changelog:
  • Add cli/CHANGELOG.md entry for 15.8.2 describing the fix and dependency update.
