iterate over the Item values rather than the Items string keys

Description:

This is also a bug in SQLAlchemy backend, an issue has been filed.

The problem is that the Items iter implementation iterates over the keys of the items (dict[string,Item]) rather than the values, so it gets a string (which is the id) instead of the Item itself. This iterates over the Items instead.

@philvarner Should we just implement the /items endpoint being able to process a feature collection? We could then add the code to stac-fastapi too potentially? Ultimately we would process a list of 'features' or items.

[philvarner]

I think we want to wait for it to be done in core stac-fastapi, and then update our impl as appropriate to however the api changes there.

Great work.
