The JS-bearing widgets now declare their script dependencies, so a view
no longer needs to know which scripts a component requires:
- SearchSelect / FilterSelect → search_select.js
- RangeSlider → range_slider.js
- DateRangePicker → date_range_picker.js
- YearPicker → datepicker.umd.js (external, from Phase 2)
- FilterBar chrome → filter_bar.js
Because the filter-bar internals now build a node tree (the legacy
Component() string-builder calls became Element/Div), each bar's
collect_media() returns its own filter_bar.js merged with the scripts
that bubble up from the FilterSelect / RangeSlider / DateRangePicker
widgets it contains — exactly the set the views thread by hand today.
Adds Node.with_media() so a function-built node can declare media
without a full BaseComponent subclass, and tests proving the bubbling.
Note: the six *FilterBar functions still share the _filter_bar chrome
helper rather than a BaseComponent class hierarchy; folding them into
one is a follow-up that does not affect media collection (Phase 4).

Introduce a FastHTML-style component model alongside the existing
function-based one, purely additive:
- Node: base renderable; __html__/__str__ render lazily so str()/f-string
composition keeps working during migration.
- Element: the single class for any HTML element (tag + attrs + children),
rendering via the existing memoized _render_element.
- Safe: wraps pre-rendered HTML (migration bridge for f-string components).
- Fragment: ordered children with no wrapper tag (replaces str(a)+str(b)).
- BaseComponent: base for higher-level components; render() returns a
subtree, media declared via a Media attribute.
- Media: declarative JS deps with order-preserving dedup merge.
- collect_media()/render() helpers walk the tree.
The legacy Component() function now builds an Element and is Node-aware in
its child handling, so a tree mixing string- and node-returning components
renders correctly with byte-identical output. No call sites changed yet.
