Add D-prefixed Blazor wrappers for every daisyUI 5 component

Components/Daisy/ wraps all 69 components in daisyUI's llms.txt, grouped by
daisyUI's categories (Actions, DataDisplay, Navigation, Feedback, DataInput,
Layout, Mockup), with part components where daisyUI has repeating parts (DTab,
DMenuItem, DTimelineItem, ...).
- Each enum maps to whole literal class names in a switch, so Tailwind's scanner
  generates them. Nothing is concatenated.
- Value-holding fields derive from DInputBase<TValue>, Blazor's InputBase, so
  @bind-Value and EditForm validation work. Invalid fields get the component's
  *-error class.
- Open and active state lives in C# (@bind-IsOpen, @bind-Active) and is rendered
  with daisyUI's *-open modifiers. DDropdown adds an outside-click layer and
  Escape. No component uses JS interop.
- The one exception is DCalendar, which wraps the Cally web component, vendored
  as wwwroot/vendor/cally.js (0.9.2, MIT).

/styleguide (not linked) renders every component in all its colours, sizes and
states, with a theme and hue picker that previews without saving.

neo.css follows what the styleguide showed:
- select keeps daisyUI's arrow;
- skeleton-text isn't sunk;
- the phone mockup and dock are raised;
- active menu items and OTP digits are inset;
- a joined accordion is raised as one block.
The primary, secondary and accent colours are deeper, so they still read as
text.
