Replaces the four onSwap-based widgets with TypeScript custom elements
following the pattern from PR #16. Each widget gets a class extending
HTMLElement with connectedCallback/disconnectedCallback, typed props via
register_element + gen_element_types codegen, and lives in ts/elements/.
- range-slider: RangeSliderElement; Python uses _RangeSlider builder
- date-range-picker: DateRangePickerElement; Python uses _DateRangePicker builder
- search-select: SearchSelectElement; Python uses _SearchSelect builder;
data-* attrs become plain attrs (data-name -> name, data-search-url -> search-url, etc.)
- filter-bar: FilterBarElement; props carry preset URLs; onclick/onsubmit
attrs replaced with data-filter-bar-* sentinel attrs; all window.* globals removed
Deletes ts/range_slider.ts, ts/search_select.ts, ts/date_range_picker.ts,
ts/filter_bar.ts. Updates all tests and e2e pages to use the new element
selectors and script paths (dist/elements/<tag>.js).

Implements the DateRangePicker design: a DateRangeField that looks like a
single input but splits each date into DD/MM/YYYY part inputs (ordered by
the new common.time.dateformat_hyphenated), and a DateRangeCalendar popup
with a preset column (today, yesterday, last 7/30 days, this/last month,
this year), anchor-style range picking with an outlined/filled/muted range
track, and a Cancel / Clear / Select footer.
Typing fills each part's placeholder from the right (YYYY -> YY19 -> 1987),
auto-advances between parts, and Backspace/Delete reverts the active part.
The committed value lives in hidden ISO {prefix}-min/{prefix}-max inputs --
the same contract as DateRangeFilter, so filter_bar.js needs no changes.
As a tryout, the Purchased filter in PurchaseFilterBar now uses the
DateRangePicker; Refunded keeps the native-date DateRangeFilter, and the
native-path e2e tests were repointed at it.
Includes unit tests for the component family and the filter-bar
integration, plus Playwright e2e tests for segment entry, calendar
picking, presets, and footer actions.
