* feat(collections): preview which of a trip's places a list already holds
The bulk import endpoint has been there since the select-mode copy, but nothing
calls it and it only reports duplicates after the fact. A dialog needs the verdict
up front, so /:id/importable/:tripId returns the trip's places with the duplicate
check the import itself applies, plus whether any day holds the place.
* feat(collections): import a whole trip's places into a list
Two steps: pick a trip, then tick its places. Places already on the list are
greyed out and unpickable, and the ones no day holds start selected — those are
the plans a trip left behind, which is the reason to import at all. Sorted so a
mostly-saved trip reads as the two that are left rather than a wall of grey.
* feat(collections): reach the trip import from the filter row and an empty list
* i18n(collections): translate the trip import into all locales
* fix(collections): stop the label dialog's buttons wrapping mid-word
Three actions in a max-w-sm footer wrapped into two lines each. The assign
button also painted white text on the accent, which disappears on a light one.
* docs(collections): document the trip import
