Forward instance config (auth, TLS, timeout, proxy, headers) to HTTPXWrapper

[mwdd146980]

Summary

• Add _build_httpx_client() that reads instance/init_config with the same field names, remapper, and priority rules as RequestsWrapper
• Update HTTPXWrapper.__init__ to accept (instance, init_config, remapper, logger) instead of a pre-built httpx.Client
• Wire basic/digest auth, TLS verify/cert, timeouts, headers, redirects, and proxy mounts; skip_proxy disables trust_env
• Update AgentCheck.http property to pass instance config through to HTTPXWrapper
• Add TestBuildHttpxClient config-parity tests and test_config_httpx to nginx unit tests

Test plan

• ddev test datadog_checks_base -- tests/base/utils/http/test_http_httpx.py -v
• ddev test datadog_checks_base -- tests/base/utils/http/test_http_backend_equivalence.py -v
• ddev test nginx -- tests/test_unit.py -v

Ship httpx_auth before enabling Kerberos/NTLM in HTTPXWrapper

When use_httpx: true is combined with auth_type: kerberos or auth_type: ntlm, this code imports datadog_checks.base.utils.httpx_auth, but that module is not present in this repository tree (datadog_checks_base/datadog_checks/base/utils/ has no httpx_auth module). That means client construction fails with ModuleNotFoundError at runtime for those auth modes, so checks cannot start with those configurations.

Require both username and password for basic auth

This enables BasicAuth whenever username is set and silently substitutes an empty string for a missing password. RequestsWrapper only enables basic auth when both username and password are provided, so on the HTTPX path a partially configured instance now sends an Authorization header that was previously omitted, which can cause unexpected authentication failures (for example, 401s) when use_httpx is turned on.
