1.0.0rc4

This is the 4th release candidate to prepare for 1.0

The upcoming 1.0 release refactors starlette-admin's internals and adds a large set of new features. The high-level
API is mostly unchanged; the one big rewrite is the list page rendering, which replaces DataTables with a server-rendered table.

See the Migration Guide for what's new, every breaking change,
and step-by-step upgrade instructions from 0.17.x.
