26.2-1.2.8: upport to mc-26.2 and new features....

[PiBOH]

➕ Added

• /opengui command — opens the DedicatedPower GUI even when the server was
  started with --nogui; reuses an already-open window instead of duplicating it
• Network menu — shows the Java server port and detects the Bedrock port from
  Geyser-Fabric config
• Tools > MOTD Editor... — professional server-hosting-style editor with:
  • live server-list-style preview
  • one-click Minecraft formatting controls (colors, bold, italic, underline, strikethrough, reset)
  • persistent MOTD history (enable/disable, delete entry, clear history)
  • enforcement of Minecraft's two-line MOTD limit
• Tools > Export Mod List... — exports installed mods to plain text (.txt)
  or a Markdown table (.md), sorted by name
• Tools > Appearance... — persistent Light/Dark mode switch + configurable log
  color palette (INFO, WARN, ERROR, DEBUG, CHAT), stored in
  config/dedicatedpower-gui.properties
• Help > System Information — shows the mod version below the Minecraft version
• Done! ASCII ready banner on server startup (works with and without Geyser),
  inspired by PiBOH/jarock
• GUI close confirmation — asks whether to close only the GUI or also shut down the server

🐛 Fixed

• Blank GUI on startup for 26.2 (NPE in buildChatPanel / logAppenderThread)
• Fabric mixin class-loading crash during server startup (GUI state moved out of the mixin package)
• GUI no longer forced open with --nogui in headless environments
• Missing top menu bar + very slow shutdown with "Close GUI and Server"
• Command input caret bug (first typed character moved to the end of the command)
• Console no longer auto-scrolling correctly / follow-bottom behavior
• MOTD editor buttons clipped by a horizontal scrollbar → buttons now wrap onto new rows
• Dark mode gaps: menu bar, palette buttons, section titles, scrollbars, check/radio
  icons, submenu arrows, accelerators, disabled items — all now theme-aware

🔧 Changed

• Ported to Minecraft 26.2, Fabric Loader 0.19.3+, Java 25
• Help menu links restored to the original project (GitHub + Modrinth)
• Full Light/Dark theming applied across log panel, player list, stats panel, menus, and dialogs

🧪 Testing

• ./gradlew clean build passes on every release; artifact dedicatedpower-26.2-1.2.8.jar
• Tested on a Fabric 26.2 dedicated server (via Jarock) with and without Geyser
• Build & Auto Release workflows run on push and via workflow_dispatch

✅ Checklist

• Build passes
• Changelog updated (CHANGELOG.md, Keep a Changelog format)
• Version bumped in version.txt and gradle.properties

I spent a few days working on it and I'm happy with how it turned out; I'd be very grateful if you accepted the pull request.
