Migrate to standard wireguard configs.

⚠️ Potentially breaking changes!

Please use migrate_project_structure.sh to migrate settings to the new structure, or manually migrate.

All situations cannot be tested (see testing). If you cannot physically access your machine, a manual migration is highly recommended.

These changes were driven by user contributions and simplifying/standardizing the installation process in preparation for Debian packaging. Future major format changes for configuration are not expected unless there are fundamental changes with Wireguard, initramfs, or the Debian packaging process requires it. Thanks to all who've contributed!

Major Changes

Added:

• Full support for wg and wg-quick during initramfs.
• Use standard wireguard adapter configs.
• Separate and simplify initramfs config in preparation for Debian packaging.
• Dual-stack (IPv4,IPv6) support with multiple interface addresses, allowed IP's lists.
• Custom MTU support.
• Test release process current requiring manual verification.

Changed:

• configs/{pre_shared_key,private_key} - removed. These are now managed in the
  wireguard adapter config and no longer needed.
• configs/config -> configs/initramfs - now installed to /etc/wireguard/initramfs.
• Documentation and tooling documentation updated.
