Review catch on #97. The chat connection test failure log interpolated
DeliveryResult.error verbatim. _deliver_webhook builds that from str(exc) on a
network error, and requests embeds the full URL in its exception text -- so the
line could carry a Discord/Slack/Teams webhook token or a Telegram bot token,
all of which live in the URL *path*. to_dict() masks `destination` even from an
admin, and /api/logs serves the log files back to the panel, so the log line
leaked past the API's own masking.
Dropping the reason would have restored the earlier problem of a failed test
button leaving no diagnostics anywhere, so it is redacted instead: URLs keep
scheme and host and lose the path, and bare bot tokens are substituted. The
host is what makes the line worth keeping and is not a secret.
Also normalise ChatWebhookConnection.raw_credentials() to {} when the stored
JSON is well-formed but not an object. A hand-edited or corrupt row could hold
`[]`, which every caller then treated as a mapping -- credentials() called
.items() on it, so to_dict() and therefore the list endpoint raised before the
write path was even reachable. Guarding at the source covers all callers and
matches the existing categories() pattern.
