Subject: [PATCH] feat(migrations): add initial VPN and Device models

Introduce initial database migration to create VPN and Device models.
These models include fields for UUID primary keys, encrypted keys,
and subnet fields, with foreign key relations to user accounts and
VPN instances. This migration sets up essential entities for the VPN
module, providing the foundational structure for VPN and device
management.
