[Bug]: Jira issue list columns crush the Issue title when the task panel is narrow (portrait screen)

### Operating system

macOS

### Orca version

1.4.188

### Details

On a portrait/vertical display (or any layout where the Tasks panel is narrower than the window), the Jira issue list picks its column grid from Tailwind **viewport** breakpoints (`md:` / `lg:` / `xl:`), not from the panel width. On a ~780px-wide panel inside a wide window the `xl` tracks apply: ~740px of fixed-width columns (Key, Status, Priority, Assignee, Updated, actions) leave the only flexible column — the issue title — with ~40px, so every title truncates to 3-4 characters.

Expected: the grid should adapt to the width of the Jira panel itself, like it does when the whole window is narrow.
