fix(dash-spv): remove deprecated ClientConfig fields from tests

Remove the deprecated enable_qr_info and qr_info_fallback fields from
network/tests.rs to match the updated ClientConfig structure. These
fields are no longer part of the configuration API.

- Removed enable_qr_info and qr_info_fallback fields from test config
- Kept qr_info_extra_share and qr_info_timeout which are still valid
- Tests compile successfully with the updated config
