- flights-map: default departure to Москва (MOW) when geolocation
doesn't yield a city. Mirrors Angular which seeds the orange
marker on Moscow regardless of geo permission. Hook now has two
effects — a synchronous MOW fallback that fires once dictionaries
load, and the existing geo callback that may upgrade to a closer
city when permission is granted.
- Schedule: introduce DayGroupedFlightList. Buckets the flat result
list by scheduled-departure date and renders each group under a
`Воскресенье 19 Апреля`-style header (Intl-driven, weekday +
genitive month). Single-day result skips the grouping noise.
- Schedule: introduce WeekTabs. Replaces the daily DayTabs in the
schedule sticky-content with Monday-anchored 7-day windows like
`13 апр - 19 апр`, matching Angular's week-tabs component.
handleWeekChange recomputes both dateFrom (Monday) and dateTo
(Sunday) when the tab changes.
- Schedule: aircraft model now visible in the collapsed FlightCard
row when `direction === "schedule"` (Sukhoi SuperJet 100 / Airbus
A321 etc., per Angular's operator-logo-and-model column).
- FlightCard / FlightList: extend `direction` union with `"schedule"`.
Tests updated: useGeolocationDefault tests now assert the MOW
fallback fires when permission is denied / API missing / arrival
already set (was previously expected to no-op).
