Add footprint preview in import dialog

Footprint Preview In Import Dialog

• Adds a click-to-preview footprint panel to the component import dialog.
• Selecting a JLCPCB part loads its real EasyEDA footprint through a restricted EasyEDA proxy, converts it to Circuit JSON, and renders it with PCBViewer.
• Selecting a KiCad footprint fetches its .kicad_mod source, converts it to Circuit JSON, and renders the result in the same preview panel.
• Existing import actions are unchanged. The preview fetch is separate from the final import flow.
• The Runframe Vercel deployment now includes a narrowly scoped /api/proxy endpoint because EasyEDA cannot be fetched directly from the browser.
