refactor: update custom STUN server settings (#1310)

* refactor: update global context STUN server initialization

Modified global context initialization to use a single StunInfoCollector
instance with properly configured IPv4 and IPv6 servers instead of
creating separate instances.

feat: add IPv6 STUN server configuration support

Added interface methods and config struct fields to support both IPv4
and IPv6 STUN server configuration. Modified getter and setter methods
to handle Option<Vec<String>> type for both server types.

feat: enhance StunInfoCollector with IPv6 support

Updated StunInfoCollector to support both IPv4 and IPv6 STUN servers.
Added new constructor that accepts both server types and methods to set
them independently.

feat: add CLI argument for IPv6 STUN servers

Added command line argument support for configuring IPv6 STUN servers.
Updated configuration setup to handle both IPv4 and IPv6 STUN server
settings.

docs: add localization for STUN server configuration

Added English and Chinese localization strings for the new STUN server
configuration options, including both IPv4 and IPv6 variants.
