feat(ui): section-heading component, dashboard spacing, sidebar-toggle icon

- Add reusable <x-section-heading> (title, muted subtitle, optional action)
  with a compact contained "View all" button; migrate dashboard Projects/
  Servers/Deployments and shared-variables environment headers to it.
- Dashboard: hide the empty active-deployments node so it no longer adds a
  gap above the first section; align section actions with the title row.
- Mobile: use the panel-left sidebar-toggle icon (matching desktop) as the
  drawer trigger instead of a hamburger.
