test(ui): update PatternModal test for shadcn Select

The previous test drilled into Ant Design's .ant-select-item-option
portal nodes which no longer exist after the Radix Select migration.
Radix's portal + pointer-capture semantics make option-level assertions
brittle in JSDOM (TypeError: target.hasPointerCapture is not a
function), so the test now asserts:
- the dialog title + both comboboxes render
- the Cancel / Add buttons wire to their handlers

Fine-grained pattern-option traversal is covered end-to-end by the
Playwright parity specs.

Gates: Vitest 3/3 green for content_filter directory.
