Original GitHub issue: https://github.com/netbirdio/netbird/issues/4911

We need to set MTU for our netbird clients to 1400. We need this because we use kubernetes cluster on Hetzner dedicated servers with vswitch. It requires MTU of 1400. More details https://docs.hetzner.com/robot/dedicated-server/network/vswitch/

Standard MTU causes unstable connection.

We can do MTU config it in desktop version of Netbird under Settings -> Advanced settings -> Connection -> MTU .

The problem is for mobile versions (Android and iOS) as there are no MTU options there. Can you add it?
