feat(ui5-table-row): add semantic click event on TableRow

[pskelin]

Summary

• ui5-table-row now fires its own custom click event when an interactive row is activated via mouse click or Enter key
• The native DOM click is intercepted in the constructor (like Button) and replaced with a CustomEvent that unifies mouse and keyboard activation
• The existing Table-level row-click event is preserved for backward compatibility
• Follows the established semantic click pattern used by Button, Link, Icon, CardHeader, and other components

This enables React consumers using createReactComponent to attach onClick handlers directly on <TableRow>:

<TableRow interactive={true} onClick={() => handleRowClick()}>

Implementation details

• @eventStrict("click", { bubbles: true }) declared on TableRow
• eventDetails.click declared on TableRowBase to maintain JSX type compatibility across the hierarchy (same pattern as SideNavigationItemBase)
• Native click suppressed via stopImmediatePropagation in a constructor-registered listener, then forwarded to the Table's event router so TableNavigation and other extensions still work
• _handleClick() fires fireDecoratorEvent("click") followed by _table._onRowClick() for backward compat

Test plan

• New test: "fires click event on the row element" — verifies non-interactive rows don't fire, interactive rows fire CustomEvent on click and Enter
• Existing row-click test still passes
• Selection tests (TableSelections.cy.tsx) all pass — RowOnly behavior unaffected
• TypeScript compiles cleanly
• New RowClick sample renders correctly on the documentation website
