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.
Remove the category-based grouping logic from ProviderPresetSelector,
letting the array position in each preset config file be the single
source of truth for display order. Move partner presets (PatewayAI,
火山Agentplan, BytePlus, DouBaoSeed) right after Shengsuanyun across
all 6 config files so they appear earlier in the UI.
