fix: follow-ups from the review of the price, Immich, moving day and import fixes

Saved place price (#2471)
- A price above zero that would be left without a currency is refused
  with a 400, over REST and through update_collection_place alike. A list
  has no base currency, so such an amount was read in each viewer's own
  default currency and went into a trip as the trip's. A price sent alone
  keeps the stored currency, and a zero price or clearing both fields
  still goes through. The check sits in the service because the MCP tool
  spreads the contract's shape, where a refine would never arrive.
- An older row that holds an amount without a currency shows it as a
  bare number instead of in the viewer's own currency.
- The Hungarian hint uses the informal register of its file, which is
  now prettier clean.

Immich certificate switch (#2475)
- The switch trusts one server. Saving a different URL without sending
  it turns it off; saving the same URL keeps it as before. The wiki says
  so.

Moving day (#2476)
- Google Maps and CoMaps are left out only when there is nothing to hand
  over. A day with a single stop opens it as a pin again, on the desktop
  and on the phone, as it did before.
- Desktop: a moving day whose flight or train has no stations shows no
  route tools, since there is nothing left to draw. With stations they
  stay.
- Phone: the drive between two stays on a day without stops or bookings
  shows once at the top instead of again at the bottom.
- The export helpers take the carrier flags as one object instead of two
  booleans in a row.

Import card (#2477)
- The success and error marks use the theme tokens.
- The e2e test names its upload with a made-up booking number.
