fix: ensure TLS handshake callback fires before HTTP request handler (#25525)

## Summary

Fixes a flaky test (`test-http-url.parse-https.request.js`) where
`request.socket._secureEstablished` was intermittently `false` when the
HTTP request handler was called on HTTPS servers.

## Root Cause

The `isAuthorized` flag was stored in
`HttpContextData::flags.isAuthorized`, which is **shared across all
sockets** in the same context. This meant multiple concurrent TLS
connections could overwrite each other's authorization state, and the
value could be stale when read.

## Fix

Moved the `isAuthorized` flag from the context-level `HttpContextData`
to the per-socket `AsyncSocketData` base class. This ensures each socket
has its own authorization state that is set correctly during its TLS
handshake callback.

## Changes

- **`AsyncSocketData.h`**: Added per-socket `bool isAuthorized` field
- **`HttpContext.h`**: Updated handshake callback to set per-socket flag
instead of context-level flag
- **`JSNodeHTTPServerSocket.cpp`**: Updated `isAuthorized()` to read
from per-socket `AsyncSocketData` (via `HttpResponseData` which inherits
from it)

## Testing

Ran the flaky test 50+ times with 100% pass rate.

Also verified gRPC and HTTP2 tests still pass.
