Upgrade Affine to version 0.16.3

[Exileum]

Upgrade Affine to version 0.16.3.

The main difference is that the local version control panel has been added. The standard username and password are no longer needed, an administrator account is created in the setup wizard.

Thanks for this update @Exileum! Really great work.

This is great that Affine now supports admin setup through the UI for self-hosted instances. Much better UX.

I have tested to make sure that existing installs retain access to their admin accounts with this update. This works for me and I am able to still sign in with the old [email protected] and $APP_PASSWORD credentials from a legacy install.

I have added info to the release notes explaining this for legacy users.
