PvP fight tracking and newer Minecraft support

Highlights

• · See your players' PvP fights as they happen - who fought who, who came out on top, and who threw the first hit - right in the live activity timeline.
• · SpawnBox now catches combat-logging: when a player disconnects mid-fight to dodge a death, the record still reflects what really happened.
• · Run the newest Minecraft - SpawnBox's combat and PvP tracking now works on Minecraft 1.21.5 and the 26.x versions, and the update reaches servers you already have.
• · Player names now show where they used to be blank: nearby players in the Activity feed, and players on plugin-based servers, resolve to real names instead of IDs.
• · Fixed three crashes some players hit after the 1.0 launch - the mods browser, the upgrade screen, and the server-info panel - plus a crash on the new fight cards.
• · Your PvP history now carries over when you switch a server's type, sessions close cleanly when players leave, and switching a server to Paper no longer stops it from starting.
• · Plus a number of smaller reliability and display fixes.
