/**
 * Tests for #1905 — editing a spool that was created without a slicer preset.
 *
 * Covers:
 * - edit/copy no longer demand a slicer preset, brand or subtype
 * - picking a preset never overwrites identity fields the user already set
 * - the Quick Add layout can't leak from create mode into an edit
 * - brand/material dropdowns rank catalog pairings instead of filtering by them
