FN-6944: reclaim quick entry textarea width

Quick entry textareas now avoid inheriting refine-button padding that caused right-side dead space.

- Override quick-entry textarea right padding with a selector specific enough to beat the shared description refine rule without !important.
- Add CSS cascade regression coverage confirming quick entry reclaims width while global description textareas retain overlay padding.
- Add a patch changeset for the published CLI package.

-The global `.description-with-refine textarea { padding-right: 70px }` (styles.css) reserves space for a refine button overlaid at the textarea's right edge. In QuickEntryBox the refine button lives in the controls panel, NOT overlaid on the textarea, so that 70px is dead space — it left a large empty gap on the right of the quick-add input (computed padding-right: 70px). Reclaim that width down to a tight var(--space-sm). Scope to the wrapping box (.description-with-refine ancestor) so this beats the global rule on specificity, not just source order (the prior `.quick-entry-textarea-wrap textarea` override tied on specificity and lost to styles.css load order). Nothing overlays the input's right edge in this variant, so text now uses the full reclaimed width.

+The global `.description-with-refine textarea { padding-right: 70px }` (styles.css) reserves space for a refine button overlaid at the textarea's right edge. QuickEntryBox renders its refine action in the controls panel instead of overlaying the textarea, so inheriting that reserve creates dead right-side text space. Scope the reclaim to the quick-entry input and include the wrapper classes so this rule beats the global description rule by specificity, not source order, while TaskForm/NewTaskModal and fullscreen description textareas keep their overlay padding.
