Refactor Linode configuration and update WireGuard settings

- Renamed SSH match block from 'vps' to 'linode' in jawz.nix for clarity.
- Updated IP addresses in toggles.nix and other configuration files to reflect the new Linode setup.
- Removed deprecated fail2ban configuration from linode's configuration.nix.
- Adjusted WireGuard interface settings to use the correct IP for linode.
- Cleaned up hardware configuration by removing unnecessary GRUB loader settings.
- Updated secrets management in wireguard.yaml to streamline key handling.
