This is because `source-field` was missing from a field dimension.

* indexed entities schema

* schema

* endpoint with create and delete

* hooked up tasks

* first tests and hooking it all together

* some e2e tests

* search

* search

had to rename value -> name. The search stuff works well for stuff that
looks the same. And previously was renaming `:value` to name in the
search result, but it uses the searchable-columns-for-model for which
values to score on and wasn't finding :value. So easier to just let name
flow through.

* include model_pk in results

* send pk back as id, include pk_ref

* rename fk constraint (had copied it)

* populate indexed values with name not value

* GET http://localhost:3000/api/model_index?model_id=135

* populate indexed values on post

done here for ease of demo. followup work will schedule the task
immediately, but for now, do it on thread and return info

* test search results

* fix t2 delete syntax on h2

* fix h2

* tests work on h2 and postgres app dbs
