Trip planner now has a consistent rounded toolbar across bookings, lists,
budget and files. Each panel shows title, inline filter pills (with
counts where useful) and an accent action button on the right. Moved
per-tab controls into the toolbar — lists import, todo add, budget
currency/add-category, files trash/filters — and dropped the redundant
in-panel headers.
Budget sidebar redesigned: total-budget card with indigo-ringed avatars
and coloured split bar; settlement flows as paired avatar cards;
by-category donut rebuilt in SVG with per-category gradients. Both cards
now follow dark/light mode via a widgetTheme helper.
Todo: add-new-task is a portalled modal on desktop, the add-task input
bar is gone; new SORT BY section in the sidebar; inline category
creation in the task editor.
Reservations: pending / confirmed sections remember their collapsed
state per trip (localStorage).
Misc: per-trip connections toggle moved into the day-plan sidebar,
booking endpoints fixed to show on map for trains/cruises/cars as well,
label localStorage persistence, RESMODAL test updated to the new
airport-select flow.
i18n: the new booking / map / todo / budget strings are translated into
all 15 supported languages.
