fix(desktop): allow worktree node_modules in vite dev server

`hgui` symlinks a worktree's node_modules to the main checkout. Vite
realpaths those before enforcing server.fs.allow, so codicon/font assets
resolved outside the worktree root and 404'd — codicons silently failed
to render in any worktree dev session. Whitelist the real node_modules
locations so the fix holds from any checkout.
