✨ (bootsier): Añade componentes esenciales

- Añade Dialog como modal de Bootstrap, con el JS de soporte para
  `htmx:confirm` y el saneado de su posición fija.
- Adapta Nav, Navbar y Dropdown al reuso de los tipos movidos al core, y
  traduce BootsierColors/Intent en Button y Badge, con soporte para
  Light/Dark vía with_color().
- Reexporta en el tema los componentes de PageTop que faltaban: Block,
  Breadcrumb, Messages, Pager, Table y form::Number.
