Dashboard: RECENT JOBS should link to GitHub Actions and show repo/workflow info

[STRRL]

Description

Two improvements for the RECENT JOBS section:

1. Clickable links: Each job entry should link to its GitHub Actions workflow run page so users can quickly jump to logs/details.
2. Show full context: Display which repo's which workflow is running on which runner, e.g. boring-design/elastic-fruit-runner / Unit Test → fruit-runner-linux-arm64-8e69f.

Expected

Each recent job row shows:

• Repository name
• Workflow name
• Which runner it ran on
• Clickable link to the Actions run page
