refactor(badges): remove redundant loading gate; fix BarChart2 deprecation

The +page.svelte {#if search_status=loading && ids.length===0} gate is now
redundant — ae_comp__badge_obj_li handles all states internally (Searching...,
Enter your name, No results). Removing it also fixes a UX regression where
trusted-user IDB fallback results would be hidden by the gate whenever a new
API search fired. Component is now always mounted and manages its own state.

Also replaces deprecated BarChart2 with ChartColumnBig (lucide rename).
