fix(ui): construct picker opens as anchored panel below the field

Search input stays in the field's own footprint (no layout jump); results
panel hangs below with a gap, solid background, stronger shadow, and a
640px width cap so option names and metadata sit close enough to scan.
Fixes the full-width overlay that visually bled into surrounding cards.
