FrankenPHP: Add env option to disable Caddy access logs

[athifsha]

This PR adds support for disabling Caddy access logs when running Laravel Octane with FrankenPHP.

Problem:
Caddy logs every request by default, creating unnecessary noise in production logs where centralized logging (Grafana, NewRelic, etc.) is already used.

Solution:
Added an environment variable OCTANE_FRANKENPHP_DISABLE_ACCESS_LOGS that, when set to true, disables the access logs by commenting out the log {} block in the generated Caddyfile.

Behavior:

Default: logs enabled (backward-compatible).

When OCTANE_FRANKENPHP_DISABLE_ACCESS_LOGS=true, access logs are disabled.

Testing:
Verified locally with Octane + FrankenPHP; access logs were correctly suppressed when the env was set.

Changelog:
Added OCTANE_FRANKENPHP_DISABLE_ACCESS_LOGS environment variable to disable Caddy access logs.

Just change it in your Caddyfile.

Got it 👍 makes sense — I’ll move the access log disable logic to our own Caddyfile instead. Thanks for the clarification!
