[management] Add idp timeout env variable (#4647)

Introduced the NETBIRD_IDP_TIMEOUT environment variable to the management service. This allows configuring a timeout for supported IDPs. If the variable is unset or contains an invalid value, a default timeout of 10 seconds is used as a fallback.

This is needed for larger IDP environments where 10s is just not enough time.
