frontend: ResourceTable: Add new 'labels' column to all list views to allow searching by label

[sniok]

fixes #2547

This PR adds a new 'labels' column (hidden by default) to all list views
This allows users to search items by label (like app=test) using the existing search bar in the table
Search works even if column is hidden, which it is by default

I've chosen the label=value format instead of label:value to keep it in line with kubectl (for example kubectl get pods -l app=agent-sandbox-controller -A)

How to test

1. Go to any table
2. type in label selector in the search bar

Pull request overview

Adds a new built-in labels column (hidden by default) across resource list views so users can search resources by label selectors (e.g. app=test) using the existing table search.

Changes:

• Extends ResourceTable column support with a new labels ColumnType, including default hidden visibility.
• Appends 'labels' to the columns list for many list views so label data participates in global search.
• Updates the Namespace list storyshot snapshot to reflect the new column behavior.

The columns array defines a custom column with id: 'labels' and then also includes the built-in 'labels' ColumnType. This results in duplicate column IDs, which can cause the later built-in column to override the custom one (and potentially break sorting/filtering/visibility). Remove the extra 'labels' entry here, or rename the custom column id (and/or set its show to false) so there is only one labels column id in the table.

This PR introduces a new hidden-by-default labels column intended to make key=value label searches work via the table’s global filter. There’s existing story-based coverage for global search (e.g., NameSearch in ResourceTable.stories.tsx), but nothing that asserts label searches work when the labels column is hidden. Add a story/test case that sets the global filter to a label selector string and verifies the matching row(s) are returned even though the column is not visible.
