Fixing json output

[SeqLaz]

This PR addresses

• CLI Auto Docs: Update API Endpoint Display: Changed the displayed API endpoint from the local development URL (localhost/api/v1/) to the official production URL (app.qfield.cloud/api/v1/).
• CLI: Standardize Login Log Output: Adjusted the login log output to ensure it consistently prints in JSON format when the --json argument is utilized. This provides more predictable and machine-readable output for users.
