[v2] Keypairs/PublicKey can not be changed

[muellpanda]

When changing keys of a client, the Peer is not updated correctly and is unreachable.

Example:

• I add a new Peer
• I exchange the generated Keys, e.g. generated keys on my local machine with wg genkey
• The PublicKey is updated correctly, but Peer is not, it holds the value of the old PublicKey (the one generated by wg-portal):

  # -WGP- Peer: FoAbkzg2cC0Gr8V9ftrxQGF1EkzUy0H6mrNsVs8Jiik=
  # -WGP- Created: 2024-05-06 14:05:32.996740905 +0000 UTC
  # -WGP- Updated: 2024-05-08 14:30:48.350186128 +0000 UTC
  # -WGP- Display name: Müllpanda
  # -WGP- PublicKey: OwItXT+oKp4Netq1sFoq/yxMn07fKcC2DDDgA2mPtRc=
  # -WGP- Peer type: client

• wg show also shows the old PublicKey, so the Peer is not reachable at all with the exchanged keypair

have you tried to disable and re-enable the peer?

I have tried to disable the peer, but it just keeps connected. It is removed correctly from the config, but wireguard itself does not get notified of the change. The peer is still listed with wg show. Restarting wg-portal (docker container) has no effect. I guess #273 is highly related.
