UniversalAdmin 1.2.1

Maintenance done right in a network: one server or all of them.

Added

• Network maintenance: /admin maintenance network on [kick] [reason]
  closes every server of the network at once (and the proxy with
  UniversalAdmin Velocity), with its own reason, message and allow-list;
  off, status, list, allow and deny likewise. The GUI page has a
  second row for it. New permission
  universaladmin.server.maintenance.network. See
  docs/user/network.md and
  ADR 0017.
• UniversalAdmin Velocity refuses logins during network maintenance
  (bypass permission on the proxy or the network allow-list still get in)
  and shows "Maintenance" in the server list (maintenance-check in its
  config.yml). /uavelocity shows both checks.
• A server in network mode without LuckPerms says at startup that OP and
  permissions count per server, and how to share them
  (network.md).

Fixed

• Maintenance in network mode was shared by accident: every server used
  the same stored state, so putting one server into maintenance closed the
  others after their next restart. Each server now keeps its own.
• /admin maintenance status and the dashboard tile also show the
  network's maintenance.
• Import summary and allow-list audit entries no longer say "1 punishments"
  or "1 players".
• UniversalAdmin Velocity names its author in the proxy log, and no longer
  uses the deprecated event order API.
• Javadoc of the extension API: no more links to classes that only exist in
  the plugin.

Upgrading

• Replace the jars (plugin on every server, and UniversalAdmin Velocity on
  the proxy if you use it) and restart. A new table (ua_maintenance) is
  created and the old maintenance state copied into it - every server keeps
  the maintenance it had. In a network, give every server a
  network.server-name if you have not yet.
