When creating/editing an instance, add '公网地址' (public_host) field.
This is the domain/IP clients will use to reach the OpenVPN server.
When downloading a .ovpn, this field is used first, falling back to:
1. ?host= query parameter (one-time override)
2. Request Host header
3. 'vpn.example.com' default
This eliminates the need to manually edit .ovpn files after download
when the server's public address differs from its internal IP.
Backend changes:
model.Instance: add PublicHost string field
service.GenerateOVPN: priority PublicHost > remoteHost > default
service.UpdateInstance: PublicHost persisted (already via JSON tag)
Frontend changes:
Instances.vue: new '公网地址' input in create/edit dialog
Instances.vue: new column in list table (shows '未配置' when empty)
Users.vue: hint text updated to '可选: 覆盖实例公网地址'
E2E verified:
public_host='vpn.yunwei.blog' → .ovpn has 'remote vpn.yunwei.blog 1194'
public_host='' + host=X → .ovpn has 'remote X 1194'
public_host set + no host → public_host wins
