Bugfix

• Fixed the encoding for EdDSA public keys. They have changed to b64 encoded DER format during the big JWT rework, when it should have been just raw bytes.
  #1018
• Added a short 3-second pre-shutdown delay to smooth out rolling releases inside K8s and also have a bit more headroom for bigger in-memory cache's replication
  #1019
• Small CSS fix to match the input width for group prefix login restriction for clients
  #1020
• In HA deployments, when the Leader was killed with an appended but not yet fully commited WAL log, there was a bug that made it possible that the log truncate would fail after restart and that the start-, instead of the end-offset would be adjusted. This has been fixed in hiqlite-wal in combination with a bump in patch version for openraft. If you run a HA cluster, you should upgrade immediately!.
