Pratik Mankawde dfcc091e7f fix(telemetry): move legend brackets into collector label, drop empty [] ...

The Display name templated the brackets: "${series} [${resource_group}]
[${iac_group}]". When a group label was absent (e.g. iac_group on a non-perf
node) the "${}" rendered empty, leaving a literal "[]" in the legend. The
empty-bracket cleanup renameByRegex could not remove it: Grafana runs that
transform on the pre-interpolation Display name template, which contains no
"[]" -- the "[]" only appears after variable interpolation, at render time.

Fix it at the source: the collector now bakes the brackets and comma separators
into the group-label VALUES (e.g. resource_group="[node, mainnet]",
iac_group="[branch, role, work-item]"). The Display name becomes bracket-free --
"${series} ${resource_group} ${iac_group}" -- so an absent group is simply an
absent label and renders as nothing. Also switches the intra-group separator
from "-" to ", " (e.g. "[node, mainnet]"). Drop the now-dead cleanup transform
from every panel; value-mapping renameByRegex rules are preserved.

Collector-side label building lives in the paired commits on the collector
config branches. This commit is the dashboard half for the eleven dashboards
this branch owns.
