fix(orchestration): contain the recipe picker dropdown + align its label

[zaridan]

Summary

Fixes two layout bugs in the New Orcastrator modal's Recipe director picker (DirectorTypePicker), both observed during live verification of the merged picker (#11). Layout/containment only — no behavior change.

1. Recipe field overflowed the modal

The trigger's SelectValue mirrored the menu item's two-line name + long description, and the trigger is whitespace-nowrap. The description's min-content (~730px) blew the field out, and CSS grid min-width:auto then stretched the entire dialog content to ~780px while the modal is only 512px wide — everything (title, labels, fields) spilled ~290px past the right edge.

Fix: the trigger now shows only the selected recipe name (single line); the description stays in the dropdown — mirroring the Project combobox above it.

2. Open menu spilled past the modal and over Cancel/Launch

shadcn's SelectContent defaults to position="item-aligned", which is unbounded and centered over the trigger, so the open menu escaped the dialog horizontally and covered the button row.

Fix: position="popper" + align="start" + width pinned to the trigger (w-[var(--radix-select-trigger-width)]), so the menu stays at field width, within the modal, and is collision-aware — again matching the Project dropdown.

Note on the "clipped Recipe label"

The reported "Recipe label clipped at the modal's left edge" was a symptom of the blown-out layout, not a separate label bug — the Recipe field was already structurally identical to the Project field. With the overflow gone, all field labels line up (verified left-aligned at the same x).

Verification

Verified live in the running dev build by measuring the actual DOM via the Electron renderer's DevTools/CDP endpoint (Screen Recording was unavailable for screenshots):

• Before: dialog 512px, but form content 781px (overflowing to x=1205); open menu 832px spilling past the modal and footer.
• After: 0 nodes overflow the dialog; trigger 462px (name-only) within bounds; open menu 462px = trigger width, contained at 424→886 ⊂ dialog 399→911; Project / Recipe / Name labels all at left=424; dropdown still lists all recipes with descriptions and selection works; trigger keeps role="combobox" + added aria-label="Recipe".
