Subject: [PATCH] feat(monitoring): restructure telegram alert template for
 readability

- Show group-level labels (alertgroup/cluster/env/namespace) once in
  the header instead of repeating them per alert.
- Use each rule's summary annotation as the per-alert headline (it
  already carries the distinguishing resource name), falling back to
  the instance label; show nodename on its own line when present.
- Drop the noisy per-alert label dump and the always-N/A value line.
