fix: track migrations; installs apply them instead of generating them

The *migrations/* ignore rule is removed. appsettings, computes and
logs pin default_auto_field to AutoField, so makemigrations --check
reports no pending BigAutoField migrations and existing installs need
no schema change.

The Vagrant provisioning no longer runs makemigrations, which created
install-specific migration files that conflict with the committed
history; it only runs migrate.
