This makes deserialization faster since entity_id columns are indexed.

* date-add => datetime-ad

It can theoretically be reconstructed on the other side, but it can be
expensive, and also causes problems when Cards depend on other Cards.
(The metadata of the parent card is needed by the child, but it is
assumed to exist, not recursively reconstructed.)

Mostly this was caused by `:id [:in []]` empty lists if eg. you don't
have any non-personal collections, or no dashboards exist.

Also I broke the argument passing to the selective dump command
`extract-subtrees` a while back and this fixes it.

Fixes #26043.
