fix(foundationdb): don't gate WorkloadMonitor behind monitoring.enabled - #3490

#4612)

## What this PR does

Fixes #4611.

Since #4148 a tenant may read the `<release>-config` ConfigMap that
holds the FoundationDB cluster file, but the console has no view for
ConfigMaps, so the connection string was still reachable only with
kubectl.

Chart:

- `<release>-resourcemap` is rendered regardless of
`monitoring.enabled`, because the console now reads it;
- the tenant Role grants `get`, `list` and `watch` on
`<release>-resourcemap` next to `<release>-config`, still by
`resourceNames`, with no wider ConfigMap access.

Console:

- the application page gets a ConfigMaps tab when the application's
resource map lists at least one ConfigMap in the same namespace;
- each listed ConfigMap is read and watched with a `metadata.name` field
selector, which RBAC checks against `resourceNames`, so a tenant never
needs `list` on all ConfigMaps;
- values are shown as plain text with a copy button, the cluster file
needs no decoding;
- a resource map that is missing or forbidden hides the tab, a listed
ConfigMap that cannot be read shows the API error instead of looking
empty, and a malformed map or an invalid name is reported.

The tab is generic, but today only FoundationDB ships a resource map, so
it is the only application that gets it.

#3490 keeps `monitoring.enabled` as the switch for the resource map and
asks whether the map should render unconditionally. This PR answers that
for FoundationDB by rendering it always, so the wording in #3490 would
need to follow if both land.

Tests: `helm unittest` for the chart (6 tests), `tsc --noEmit`, `vitest
run` (438 tests in 60 files) and `eslint` on the changed files pass. The
new tests cover reading only the listed names in the active namespace,
the watch, copying, a clipboard failure, a read denial, and malformed
maps. The chart renders with `monitoring.enabled` true and false.

### Screenshots

console from this branch against a local stub API with synthetic data:

### Downstream repositories

Walked the trigger map against the diff: it changes a FoundationDB chart
template and its test, and the console. No `values.yaml`,
`values.schema.json`, README, CRD or `hack/` file is touched. The
website FoundationDB page is generated from the chart README and says
nothing about connecting, and the Terraform provider does not read these
ConfigMaps. The console is vendored in this repository.
