The alert detail panel dumped a.Settings raw — SMTP passwords, bot
tokens, API keys on screen and into any recording or screen share. The
table view leaked the PagerDuty routing key, Pushover user key, and
full discord/slack/webhook URLs (the URL path is the credential).
The redaction allowlist moves from internal/server to
models.RedactAlertSettings so the backup export and the TUI render
through one policy. Panel keys are sorted so rows stop reshuffling
every tick; webhook URLs show scheme+host only; keys show
first4…last4.
