Dashboard inline editing

[OlhaTmlk]

Description

Summary

• Added inline editing for dashboard names on the generic dashboard page — users can click a pencil icon next to the dashboard title to rename it in place
• Added a rename API function (renameDashboardTemplate) and integrated it into the useDashboardTemplate hook so the updated name reflects immediately without a full page refetch
• Added renameDashboardAtom to keep the dashboards list in sync after renames
• Add Playwright E2E tests for inline renaming (confirm + verify in Dashboard Hub) and cancel editing (verify original name preserved)

Details

• GenericHeader: Toggles between a read-only title and an editable TextInput with confirm/cancel buttons. Supports Enter to confirm and Escape to cancel.
• useDashboardTemplate: New renameDashboard callback that calls the API and optimistically updates local dashboard state.
• API: New renameDashboardTemplate function calling PATCH /api/widget-layout/v1/{id}/rename.
