fix: declare proxy ARGs in build stage so dotnet restore reaches nuget.org

Browse Source 
nuget.org is only reachable through the 7890 proxy from the build network
(direct hits return a 302 redirect loop; proxied requests return 200,
verified 8/8). The pipeline passes --build-arg HTTP_PROXY/HTTPS_PROXY, but
Dockerfile did not declare these ARGs in the build stage, so buildkit did
not inject them into the RUN environment and 'dotnet restore' tried nuget.org
directly -> NU1301 'Unable to load the service index'.

Declare HTTP_PROXY/HTTPS_PROXY/NO_PROXY (upper+lower case) as build-stage
ARGs and promote them to ENV so dotnet's HttpClient uses the proxy. Also add
two restore retries (--disable-parallel) to smooth over transient proxy
blips.
