luci-app-wireguard: "Import Configuration as peer..." imports wrong data

### Package Name luci-app-wireguard ### Maintainer @Environment ### OpenWrt Version 25.12.5 ### OpenWrt Target/Subtarget mediatek/filogic ### Steps to Reproduce 1. Go to Network -> Interfaces 2. Edit -> wireguard Interface 3. Go to Peers and use the tool "Import Configuration as peer..." 4. Drag &drop wg.conf in the field ### Actual Behaviour When the succesfull imported Peer is analyzed it always inserts wrong content. - Public Key is wrong and not whats is in the e.g. Mullvad wg.conf content. Also what I've noticed: - Allowed IP's, Endpoint Host, Endpoint Port, is also not imported(+Route Allowed IP's). But at least it doesn't insert incorrect data. So after using the tool the Peer isn't working and some will have a bad time don't knowing why the tunnel isn't working. I always had to manually insert the content from the wg.conf into the peer configuration and by luck managed to spot the problem. ### Confirmation Checklist - [x] The package is maintained in this repository. - [x] I understand that issues related to [the base OpenWrt repository](https://github.com/openwrt/openwrt/issues) or [LuCI repository](https://github.com/openwrt/luci/issues) will be closed. - [x] I am reporting an issue for OpenWrt, not an unsupported fork.
