Add DateRangePicker component with segmented entry and calendar popup

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.

+"""DateRangePicker: a segmented date-range input with a calendar popup.
+
+``DateRangePicker`` composes two parts:
+
+- ``DateRangeField`` — the visible widget, styled as a single input. Each
+  date is split into per-part segments (``DD``/``MM``/``YYYY``, ordered by
+  ``common.time.dateformat_hyphenated``) that the user fills digit by digit,
+  plus a calendar icon that opens the popup.
+- ``DateRangeCalendar`` — the popup: a preset column (today, yesterday,
+  last 7 days, …), a month grid rendered client-side, and a
+  Cancel / Clear / Select footer.
+
+The committed value lives in two hidden ISO-date inputs named
+``{input_name_prefix}-min`` / ``{input_name_prefix}-max`` — the same contract
+as the older ``DateRangeFilter``, so ``filter_bar.js`` serializes either
+widget into a ``DateCriterion`` unchanged. All behaviour is wired by
+``games/static/js/date_range_picker.js``.
