UniversalAdmin

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.
