dob-oai b538d2b340 Preserve WebSocket probe evidence and redact diagnostic details (#57597) ...

## Why

Handshake probes can lose upgrade evidence when a subsequent read fails, and diagnostic output can expose URLs, server error messages, and close reasons containing sensitive values.

## What changed

- Retain successful upgrade status and allowlisted tracking headers, including on post-upgrade read failures.
- Return structured probe errors that distinguish typed TLS failures from failures with an unknown stage while preserving the underlying API error.
- Recognize empty close frames as immediate closes with code `1005`.
- Redact wire values from probe debug output and doctor error details, and remove URLs and raw errors from connection logs.

## Testing

Add local TLS and WebSocket fixtures covering certificate rejection, ordinary I/O failures, successful and rejected upgrades, immediate closes, malformed frames, header retention, and redaction. Add doctor output snapshots and error-detail redaction assertions.
