Implements task #7. The Hosts page provides:
- Name/network/port/application filters (sentinel values instead of
Option<T> to avoid server function serialization issues)
- Configurable page size (15 default, 25/50/100/All)
- Prev/next navigation with total host count
- Add host form with network selector
- Delete action per row
Sub-components (AddHostForm, FilterBar, PaginationBar, HostTable) each
call .into_any() to erase their concrete view types. This breaks the
deeply-nested generic type that caused "queries overflow the depth
limit!" without requiring an unbounded recursion_limit increase.

Introduces a global design system using CSS custom properties as
design tokens. Light and dark themes are defined via [data-theme]
attribute on <html>; the system preference (prefers-color-scheme)
is the default when no explicit choice is stored.
ThemeToggle component (Auto → Light → Dark cycle) persists the
choice to localStorage and applies it on hydration without flash.
New themes can be added by defining a [data-theme="name"] CSS block
and adding a variant to ThemeChoice.
