Maurice 8864edda18 feat(budget): link existing expenses to bookings and places, several per booking ...

Discussion #2084: a cost bought later (the seat upgrade for a flight) could
not be tied to the booking it belongs to, and a booking held one expense.

- The Costs block of the booking, transport and place forms lists every
  linked expense with edit, unlink (the expense stays in Costs) and delete,
  and offers the expenses that belong nowhere yet under Link existing
  expense. The phone sheets get the same block in their own design, and
  their Files row lists the attached files and links an existing one.
- PUT /budget/:id, update_budget_item (MCP) and costs.update (plugin RPC)
  take reservation_id / place_id; create and update refuse an id from
  another trip on all three paths.
- The booking's mirrored price is the sum of its expenses when they share
  one currency (none counts as the trip's), else the first one, with that
  currency, and follows every change to a linked expense. The booking
  form's price field leaves a booking with several expenses alone.
- Deleting a booking deletes all of its linked expenses and broadcasts each
  one, also from the MCP delete tools.
- Cards show the price with its currency.
- Booking and transport dialogs: Booking Type and Travelers as dropdowns at
  the top, the URL beside Files (transports gain the URL field). The row is
  one shared component; linking and unlinking files go through the store.

Help center pictures and texts for the booking, transport and expense
guides are redone in all 27 languages, five Costs labels that were still
English in 16 languages are translated, and the wiki follows.
