fix: add browser headers to all API requests to resolve 403 on usage endpoint

Claude's usage/prepaid/overage endpoints require Origin, Referer, and
User-Agent headers to pass CORS/auth checks. Without them, bootstrap
succeeds (more permissive) but usage returns 403 -> 'Not signed in'.

Added claudeAPIRequest(for:) helper that sets all required browser-like
headers on every request. Bootstrap, usage, prepaid, overage, and the
orgs fallback all go through it.

 - Fixed login window auto-closing before the user could sign in — the login window now correctly loads the `/login` page so it only detects auth after the actual sign-in redirect
 - Fixed "No API key configured" showing after signing out — now correctly shows "Not signed in" with a prompt to sign in
 - Added `/api/organizations` as a final fallback for org ID resolution when the bootstrap API response doesn't include it
+- Fixed usage data not loading after sign-in — API requests now include required browser-like headers (Origin, Referer, User-Agent) that Claude's usage endpoints require
