NO_PROXY env var not working

[24berickson]

Bug description

NO_PROXY environment variable is not respected by Prisma Client Python when connecting to query engine. Even with NO_PROXY set correctly for localhost/127.0.0.1, connections are still being routed through proxy, resulting in 403 Access Denied errors.

How to reproduce

1. Set up Prisma Client Python in an environment behind a corporate proxy
2. Set NO_PROXY environment variable:

os.environ["NO_PROXY"] = "localhost,127.0.0.1"

3. Try to connect to Prisma query engine:

async with Prisma(http={"trust_env": True}) as prisma_client:
    # Any query attempt results in proxy intercepting local connection

4. Error received 403 when trying to access http://localhost:60367/status as it was being routed to proxy.

Expected behavior

1. Prisma Client Python should respect NO_PROXY environment variable
2. Local connections to query engine should bypass proxy when NO_PROXY is set correctly
3. Similar behavior to other Prisma clients regarding proxy handling (Node.js working as expected I believe)

Environment & setup

• OS: Mac OS
• Database: PostgreSQL
• Python version: 3.11
• Prisma version: 0.15
