fix(telemetry): make Tempo search filters dynamic

Change the six remaining `type: static` search filters in tempo.yaml to
`type: dynamic` so Grafana queries Tempo for available tag values instead
of requiring manual free-text entry. Aligns service-name, node-id,
network-type, span-name, span-status, and span-duration with the existing
node-version and network-id filters.
