fix(net): prefer TLS for getConfiguration requests

[rafaadeveloper]

Goal of this PR

Make getConfiguration prefer HTTPS instead of always using plaintext HTTP when connecting to the game endpoint.

This removes the mandatory plaintext path for the configuration request while preserving compatibility with servers that may still require the legacy HTTP behavior.

How is this PR achieving the goal

• Attempts to fetch getConfiguration over HTTPS first.
• Falls back to the existing HTTP path only when the TLS request fails at the transport level.
• Preserves the existing request payload and response handling.
• Avoids masking valid HTTP responses or server-side errors by only retrying when no HTTP response was received.

This PR applies to the following area(s)

• FiveM
• Networking
• Client connection flow
