Port FastHTML's proc_htmx as onSwap(selector, initializeElement) in
utils.js, built on htmx.onLoad: it runs an initializer once per matching
element, on initial page load and inside every htmx-swapped fragment.
Migrate search_select.js, range_slider.js, filter_bar.js and
add_purchase.js to it, removing the hand-rolled DOMContentLoaded +
htmx:afterSwap listeners and per-element guard flags. This also fixes a
latent bug: both events passed the Event object as range_slider's
"force" parameter, so every htmx swap force-re-initialized all sliders
and stacked duplicate listeners. The collapse button's
window.initRangeSliders() call was a no-op (handles are positioned in
percentages, so hidden-init is safe) and is removed with the global.
Add e2e/test_widgets_e2e.py covering the onSwap lifecycle (initial-load
init, htmx-swap init, single-fire toggles) plus FilterSelect pills and
the add-purchase type toggle. The synthetic page in
test_search_select_e2e.py now loads htmx and search_select.js as a
module, matching the new initialization path.

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.
