fix: update WireGuard Easy template for proper functionality (#573)

* fix: update WireGuard Easy template for proper functionality

- Changed to named volume (etc_wireguard) instead of host path mount
- Added explicit port mappings (51820:51820/udp, 51821:51821/tcp) required for WireGuard
- Updated environment variables to use correct WG_HOST and PASSWORD format
- Added all required WireGuard environment variables:
  - WG_PORT, PORT, WG_MTU, WG_DEFAULT_DNS, WG_ALLOWED_IPS
  - WG_POST_UP/WG_POST_DOWN for iptables rules
- Added NET_RAW capability for proper network operations
- Simplified template.toml to use WIREGUARD_HOST and WIREGUARD_PASSWORD
- Removed explicit networks config to enable Dokploy's isolated deployment
- Template now works with Dokploy's automatic network isolation

This configuration has been tested and confirmed working with isolated deployment enabled.

* Update template.toml
