feat(datatable): add bottom selected text

[paanSinghCoder]

Description

feat: add hidden by filters text

Three scenarios:

• Server + totalRowCount: show exact hidden count (X items hidden by filters) using API total and loaded/visible rows.
• Server without totalRowCount: show only generic hint (Some items might be hidden by filters) when filter/search is active.
• Client with full data: compute exact hidden count locally from pre-filter vs post-filter rows and show it when > 0.

📝 Walkthrough

Walkthrough

This change introduces a "Filter Summary Footer" feature to the DataTable component. A new optional totalRowCount prop is added to the DataTable interface and context to support server-mode row tracking. The Content component now conditionally renders a footer when filtering is active, displaying either a calculated hidden-row count (for client mode) or the provided totalRowCount (for server mode) alongside a "Clear Filters" button. Three new utility functions (countLeafRows, getClientHiddenLeafRowCount, hasActiveTableFiltering) support the filtering logic. Corresponding CSS styling, tests, and documentation updates are included to complete the feature.

Title check	❓ Inconclusive	The title 'add bottom selected text' is vague and does not accurately describe the actual change, which adds a filter summary footer showing hidden row counts and clear filters functionality.	Revise the title to more clearly describe the feature, such as 'feat(datatable): add filter summary footer with hidden row count' or similar.
