Avoid sqlalchemy dep

[danielballan]

Description

tiled.adapters.utils has a sqlalchemy dep now, so the utility IndexerMixin was moved to tiled.utils in bluesky/tiled#1206.

Motivation and Context

Import error:

How Has This Been Tested?

We don't have the harness set up to test a client-only install on CI, but this resolves the issue in a local test.

E ImportError: cannot import name 'tree_repr' from 'tiled.utils' (/opt/hostedtoolcache/Python/3.12.11/x64/lib/python3.12/site-packages/tiled/utils.py)

That looks real and caused by this change.
