Subject: [PATCH] feat(grafana): custom emoji message templates per alert +
 resolve format
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each alert rule's summary annotation now renders a formatted Telegram
message with emoji and multiline context. The contact point passes the
pre-rendered summary through, adding "✅ Resuelto" on resolution.
Also restores the == 1 filter on Pod Failed/Unknown lost in prior rebase.
