Cleaner page titles, new jobs page, cancel confirmation

Navigating and managing jobs is snappier with a tighter header, a dedicated jobs page, and safer cancellation.

🚀 What’s New

• Jobs page – view all jobs in one place with statuses and links.
• Cancel confirmation – confirm before stopping a running job to avoid mistakes.

🔧 Improvements

• Page titles – headers take up less vertical space for better above‑the‑fold content.
