fix(api): fix for ListAppKeys() not returning app keys (#10465)

# Which Problems Are Solved

`ListAppKeys()` does not work properly, in that it does not return any
app keys.


# How the Problems Are Solved

The issue stems from a mistake SQL query not joining the
`projections.authn_keys2` table to `projections.projects4` instead of
joining to `projections.apps7`

# Additional Changes

`ListAppKeys()` returns the app key IDs in order of their creation

- Closes https://github.com/zitadel/zitadel/issues/10420
- backport to v4.x
