fix: align run controls with queue modal design (#9134)

## Summary
- move queue batch controls to the left of the run button
- align run control styling to the Figma queue modal spec using PrimeVue
PT/Tailwind (secondary background on batch + dropdown, primary run
button)
- normalize control heights to match actionbar buttons and tighten
dropdown hit area
- update run typography/spacing and replace all three chevrons (dropdown
+ batch up/down) with the requested SVG
