dashboard Show count of items in list group's tag

Summary

Fixes #15537

When viewing large resource lists grouped by namespace, there's no way to quickly identify which namespace contains the most resources without using the namespace filter. This adds a count indicator to each group tab using the COUNTs data from the store, which provides accurate total counts per namespace regardless of pagination.

Occurred changes and/or fixed issues

Group tabs now display item count: Namespace: cattle-system (1519) instead of Namespace: cattle-system
Only applies to "group by namespace" grouping (supports both namespace and metadata.namespace group values)
Uses store COUNTs data for accurate total counts (works correctly with pagination)

Technical notes summary

Modified ResourceTable.vue to use the store's COUNTs data for namespace counts:

Added COUNT import from @shell/config/types
Added namespaceCounts computed property to retrieve namespace counts from the store
Added showNamespaceCounts computed property to only show counts for namespace grouping (checks for both namespace and metadata.namespace group values)
Updated the group-by template slot to conditionally display counts:

<template #group-by="{group: thisGroup}">
  <div class="group-tab">
    <span v-clean-html="thisGroup.ref" />
    <template v-if="showNamespaceCounts">
      <span
        v-if="namespaceCounts[thisGroup.rows?.[0]?.metadata?.namespace]"
        class="count"
      >
        ({{ namespaceCounts[thisGroup.rows?.[0]?.metadata?.namespace].count }})
      </span>
    </template>
  </div>
</template>

Count styled with opacity: 0.7 and margin-left: 2px to visually distinguish it from the namespace name.

Areas or cases that should be tested

View any namespaced resource list (Pods, Deployments, Services, etc.)
Enable "Group by Namespace" via the grouping button
Verify count appears in parentheses after each namespace name
Verify count shows total resources per namespace (not just current page count)
Verify count is correct when pagination is enabled with different page sizes
Test with both standard and paginated resource tables
Tested in Chrome; reviewer should test Firefox/Safari

Areas which could experience regressions

Custom grouping implementations that override the group-by slot
ResourceTable consumers with custom group label rendering
Other grouped views (Fleet, etc.) that use the same component

Original prompt

This section details on the original issue you should resolve

<issue_title>Show count of items in list group's tag</issue_title> <issue_description>Is your feature request related to a problem? Please describe.

recently i was looking at 2.5k pods in pods list, with default page size of 100, grouped by namespace

in order to understand which namespace contained the majority of the pods (to debug why so many) i had to use the ns filter

Describe the solution you'd like

this isn't a biggy, but we should have the pods by namespace in the counts object and it would be super convenient to show that in the group tag Namespace: cattle-system (1519)

i think we could do this generically for all grouped by namespace groups

we could do for all other ways to group with vai off , but not with vai on. for this reason i think we should just stick to group by namespace

@copilot this solution won't work with pagination. Can you update it to only apply to the 'group by namespace' group and in that case, to use the data we have in the COUNTs data in the store, which provides counts of resources by namespace.

Updated in 1adb906 to use the COUNTs data from the store. The implementation now:

Only applies to "group by namespace" grouping
Uses namespaceCounts computed property that retrieves counts from $store.getters[inStore/all](COUNT)[0]?.counts[schema.id]?.namespaces
Correctly shows total count per namespace regardless of pagination

@copilot this doesn't quite work - the check for the namespace group should allow metadata.namespace as well asnamespace. Can you fix that and also reduce the padding from 5px to 2px. Thanks

Fixed in 2f2704a:

Updated showNamespaceCounts to check for both namespace and metadata.namespace group values
Reduced margin-left from 5px to 2px
