Some improvments flagged by Repo-Review: https://learn.scientific-python.org/development/guides/repo-review/

1. Remove now-default show_error_codes.
2. Enable some optional error codes with extra checks.

Fixes #460.

Just being explicit.

Vestigial from pyupgrade skeleton.

Fixes #344.

Handles both forms of `index_together`, in list and tuple, and
with/without existing `indexes` definition. Tried to cover every edge
case I could think of, per tests.

Tested on Sentry, the only project I could find with historical
`index_together` definitions. Use this commit:
getsentry/sentry@a32270c,
just before
github.com/getsentry/sentry/commit/00884d133eaaedf3e69bc8ab3d3bca781e0c425f
and later commits updated `index_together`.

Saw successful rewrites:

One model was missed due to no `from django.db import models` in the
file - I am gonna leave that for extension, if anyone wants.
