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.

 ### Bug fixes
 - Fixed "Not signed in" showing incorrectly on launch when the session was already active
 - Sign-in state is now detected immediately from stored cookies on startup, before the first data refresh completes
-- Fixed Re-authenticate (and Sign In) not detecting an existing session — the login window now loads `claude.ai` directly so already-signed-in users are detected correctly and the window auto-dismisses
+- 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
-- Session cookie detection now checks both `sessionKey` and `__Secure-next-auth.session-token` cookie names
+- 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
