Add global TLS verification skip setting

Adds a new boolean setting in the Advanced settings group that allows
users to globally skip TLS certificate verification for all enhanced
apps. This is useful for users who have self-signed certificates on
their services.

When enabled, the Guzzle HTTP client will set 'verify' => false for
all API requests made by enhanced apps.
