Garrett Delfosse 4057363f78 fix(coderd): add organization_name label to insights Prometheus metrics (#22296) ...

## Description

When multiple organizations have templates with the same name, the
Prometheus `/metrics` endpoint returns HTTP 500 because Prometheus
rejects duplicate label combinations. The three `coderd_insights_*`
metrics (`coderd_insights_templates_active_users`,
`coderd_insights_applications_usage_seconds`,
`coderd_insights_parameters`) used only `template_name` as a
distinguishing label, so two templates named e.g. `"openstack-v1"` in
different orgs would produce duplicate metric series.

This adds `organization_name` as a label to all three insight metric
descriptors to disambiguate templates across organizations.

## Changes

**`coderd/prometheusmetrics/insights/metricscollector.go`**:
- Added `organization_name` label to all three metric descriptors
- Added `organizationNames` field (template ID → org name) to the
`insightsData` struct
- In `doTick`: after fetching templates, collect unique org IDs, fetch
organizations via `GetOrganizations`, and build a
template-ID-to-org-name mapping
- In `Collect()`: pass the organization name as an additional label
value in every `MustNewConstMetric` call

**`coderd/prometheusmetrics/insights/testdata/insights-metrics.json`**:
Updated golden file to include `organization_name=coder` in all metric
label keys.
