fix: resolve critical bugs and security issues across the project

- Fix GPS map links always sending literal "latitude"/"longitude" strings
  instead of actual coordinates in openLocation/Content.js
- Add api.clinic-pro.ir to next.config.js remotePatterns so production
  images load correctly
- Fix appointment page: await params and getStateInfo (Next.js 15 pattern)
- Enable 401 handling in api.js: clear cookies and redirect to /login
- Move OAuth client_secret to server-side API routes (/api/auth/token,
  /api/auth/refresh) so it is never bundled into client-side JavaScript
- Update SendReq, SubmitData, ButtonSendData to call API routes instead
  of directly sending client_secret from the browser
- Update docker-compose.yml to use server-only CLIENT_SECRET env var
- Remove debug console.log from clinic doctors list component
