refactor: redesign dashboard UI

- Replace large 200x200 icon tiles with compact horizontal nav cards
  (icon + title + description, grid-wrapped, responsive)
- Split single Settings card into separate Overlay and Integrations
  cards, each with its own Save button and status indicator
- Fix canvas save wiring bug: add missing #save-canvas-btn and
  #canvas-status elements that were referenced in JS but absent from HTML
- Remove silent saveCanvasSettings() side-effect from saveScriptSettings()
- Replace window.prompt delete confirmation with inline two-step confirm
  flow (Delete button → confirm panel → cancel/confirm)
- Add danger-zone collapsible section with danger-border styling
- Add responsive media queries: topbar stacks on narrow viewports,
  nav cards and dashboard grid collapse to single column below 700px
- Remove dead CSS classes (dashboard-action, dashboard-tile,
  dashboard-toggle-tile, large-dashboard-tiles, etc.)
- Merge near-duplicate renderAdmins/renderSuggestedAdmins into single
  parameterised renderAdminList() helper
- Remove unused addVersionAttributes() call from dashboard route
