Subject: [PATCH] Stabilize Jobs pane layout

Replace the resizable HSplit on the Jobs tab with a border layout that keeps the job list pane at a stable minimum width.

The left pane now uses a small custom layout that asks Fyne for the content minimum size and applies at least 480 logical pixels. This prevents the divider from moving when the selected job changes while still allowing the toolbar buttons, including Delete, to fit when their calculated minimum width is larger.

Only the Jobs tab layout is changed; settings, storage, scheduler behavior, and documentation are intentionally left untouched.
