Code Issues Proposed changes

Ensure Horizon mod_wsgi uses global WSGI subinterpreter

Browse Source 
Cryptography changes implemented in Rust are using PyO3, which does not support multiple subinterpreters.

To address this, the Apache configuration for Horizon has been updated to ensure that the WSGI server uses the global Python interpreter.

This change ensures compatibility with the new Rust-based cryptography implementation and prevents potential issues with request handling.

Changes:
- Updated the Horizon Helm override configuration in conf.horizon.apache inside the VirtualHost directive.

Test Plan:
- PASS: Confirm that no errors related to subinterpreters appear in Horizon logs.
- PASS: Ensure that Horizon responds with HTTP status code 200 upon accessing the main page.

Reference:
- PyO3's lack of support for subinterpreters:
