Your Dialog acts as a router but it has to be on the same sub network no cross network LAN to WAN is possible.
No need to make multiples policies or static route it's too complicated for a simple need. I can't ensure it will work without a high end hardware
Pinging is not everything some protocols only work on the same sub net or LAN
Creating a VLAN sounds good to me. Spark app should be installed on a computer with an IP leased on the right LAN.
Buy a managed switch 4 ports (or more) and connect it on a dedicated LAN (VLAN) port on your FortiWifi 30E.
If your Iphone is connected to 192.168.3.1 or 192.168.5.1 it can't work... your Iphone's IP must be using this IP range 192.168.11.x
