fix: redact secrets and ids from panel dry-run logs

CodeQL flagged clear-text logging of sensitive information in the panel
dry-run logger: it dumped the full request payload (which can include
proxy credentials like trojanPassword/ssPassword and PII such as email
and telegramId) and the raw endpoint (embedding user UUIDs).

Recursively redact values under sensitive keys before building the
payload preview, and mask opaque id-like segments in logged endpoints.
