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.
- Remove obsolete spice-html5 static assets and SPICE console templates
- Restrict default console types to VNC with migration 0012
- Filter out SPICE in VM creation form and backend capabilities
- Return friendly deprecation notice if legacy VM is opened with SPICE
- Clean up docs, architecture references, and libvirt-bootstrap scripts
