feat(11-04): add client-side search bar to catalog page, remove ServiceForm

- New CatalogSearch client component: filters ServiceWithTags[] by name/tag, case-insensitive, instant (no reload)
- page.tsx now passes filtered services through CatalogSearch -> ServiceTable
- ServiceForm.tsx deleted — quick-add row in ServiceTable replaces its create-service UX
