feat(ai): add suport for /ai set custom parameters

Browse Source 
Modify _build_json_payload_from_list to accept an AIProvider parameter
and dynamically merge its custom settings into the JSON payload. The
settings are serialized as additional key-value pairs alongside the
standard model and input fields, enabling per-provider configuration
options without hardcoding them.
