refactor(ext/popup): rename entry-* → item-* components

Git-moves the three popup components so history survives the content
rewrite that follows in Tasks 22–24:
- entry-list.ts   → item-list.ts
- entry-detail.ts → item-detail.ts
- entry-form.ts   → item-form.ts

Also renames the exported render functions (renderEntryList →
renderItemList, etc.) and updates popup.ts imports + render switch.
The files still wear @ts-nocheck and reference the old Entry type;
content rewriting happens in Tasks 22–24.
