fix(providers): scope preset search to provider names only

The preset search text also included websiteUrl and the shared category label, producing imprecise matches: a single category term matched the whole group, and URL fragments like "com"/"api" matched nearly everything. Restrict the search text to the display name and raw name; category labels are still used for rendering.
