feat: add dlp: false passthrough option for egress routes
Routes with `dlp: false` skip all DLP scanning (including CRLF injection,
which cannot be disabled via `dlp.outbound_detectors: false`) and tunnel
HTTPS connections without TLS interception so the client sees the server's
real certificate. Fixes Docker image pulls, which fail when the proxy MITM's
the TLS handshake and the container doesn't trust the per-bottle CA.

Closes #462
