fix(web): distinct extension-format icons (plugin/mcp/skill)

The format filter used Wrench/AudioWaveform/Book for plugin/mcp/skill,
which collided with the plugin-component icons (Tool/EventListener/
KnowledgeEngine) shown right below. Switch formats to Puzzle/Server/
Sparkles — matching the canonical getTypeIcon used by the detail badges
— across the market filter, installed filter, install-queue map and
install-progress dialog.
