fix: rename "breached" to "threshold exceeded" in user-facing strings

Only changes user-facing text — no enum, type, or backend status changes.

## Changes
- locales/en.json: "breached" → "threshold exceeded"
- notificationMessageBuilder.ts: notification title/summary/details
- email.ts: email subject line
