viyatb-oai e4dba902ab Support caller-provided MITM CAs in the network proxy (#47132) ...

## What changed

- Add optional `network.mitm_ca` configuration with `certificate_file` and
  `private_key_file` for trusted proxy configuration. Require MITM to be enabled
  and retain the generated CA when no external CA is configured.
- Validate absolute paths, regular files, file sizes, certificate/key matching,
  and Unix private-key permissions. Reject symlinks on Unix, private keys embedded
  in certificate files, and external private keys on non-Unix platforms.
- Store derived external-CA trust bundles in the proxy artifact directory,
  include only certificates, and skip inherited generated bundles to avoid
  retaining stale roots.
- Preserve MITM for external CAs when disabling credential brokerage. Reject
  external CA configuration for remote execution, even when the proxy is disabled,
  and reject unknown fields in `NetworkProxyConfig`.
- Default the upstream request version adapter to HTTP/1.1 and remove the request
  URI from upstream request failure context.

## Testing

Add regression coverage for external CA configuration, mismatched keys, embedded
private keys, non-Unix rejection, trust-bundle placement and contents, stale-root
exclusion, credential-broker toggling, and remote configuration rejection.
