scooby87 f91841fce6 fix(monitoring): surface missing VictoriaLogs and gate dead-end vlinsert ExternalName (#3215)
## What this PR does

Addresses #3181, where platform log ingestion could fail **silently**:
fluent-bit shipped to `vlinsert-generic` while the monitoring
`HelmRelease` reported `Ready`, and a `vlinsert-generic` `ExternalName`
in `cozy-monitoring` dead-ended at a `tenant-root` VictoriaLogs that did
not exist when the root tenant had monitoring disabled. Logs were
dropped with no failing signal.

Three complementary layers make the failure loud instead of silent:

1. **Readiness gate** —
`packages/extra/monitoring/templates/helmrelease.yaml` now sets a
`poller` `waitStrategy` and a `healthCheckExprs` entry on the
`VLCluster` `status.updateStatus`. A missing/unhealthy log store makes
the `monitoring-system` release **not-ready** instead of flipping
`Ready` the moment the CR is applied. Mirrors the existing seaweedfs
CNPG pattern.
2. **No empty-log-store hole** —
`packages/system/monitoring/templates/vlogs/vlogs.yaml` fails the render
on an empty `logsStorages`. With no entry no `VLCluster` exists, the
readiness gate has nothing to match, and fluent-bit would silently drop
logs — so this is now a loud misconfiguration.
3. **No silent fallback** — the `cozy-monitoring → tenant-root`
`vlinsert`/`vminsert` `ExternalName` redirects in `cozystack-basics` are
created only when the root tenant hosts monitoring. The template reads
the live `Tenant/root` `spec.monitoring` via `lookup` (source of truth,
so it cannot drift from the tenant's real state) and falls back to a new
platform value `monitoring.rootEnabled` (via
`_cluster.monitoring-enabled`) when `lookup` is empty (dry-run / first
render). The default preserves the historical always-create behaviour.

Covered by helm-unittest across all four affected charts (141 tests):
readiness-gate fields, empty-vs-populated `logsStorages` contract,
`ExternalName` present/absent fallback contract, and the platform wiring
into the `cozystack-values` Secret. Also adds the missing `test:` target
to `packages/extra/monitoring/Makefile` so its suite runs in CI.

**Known limitation / follow-up:** the legacy platform monitoring release
installed directly into `cozy-monitoring` via the `cozystack.monitoring`
PackageSource cannot carry the readiness gate, because the engine's
`ComponentInstall`/HelmRelease builder and the vendored
`helm-controller` API v1.4.3 lack `waitStrategy`/`healthCheckExprs`.
That source is not referenced by any active bundle; full coverage there
needs a helm-controller bump plus engine support.

## Summary by CodeRabbit

* **New Features**
* Added a platform setting (`monitoring.rootEnabled`) to control whether
root-level monitoring is enabled.
* Monitoring redirect ExternalName services are now rendered only when
root monitoring is enabled (defaulting to enabled).
* **Bug Fixes**
* Ensures an explicitly set `monitoring.rootEnabled=false` is preserved
when generating platform configuration.
* Prevents incomplete monitoring deployments by failing rendering when
`logsStorages` is empty.
* Improves VictoriaMetrics readiness by delaying “ready” until the
operator reports an operational status.
* **Tests**
* Added/expanded Helm-unittest suites covering monitoring wiring,
redirects, readiness gating, and `logsStorages` requirements.
  * Added a `make test` target to run chart unittests.
