Add clickable message IDs and action buttons to mailbox UI

[Copilot]

Players can now click message IDs directly from list views to open messages, and use clickable [Archive]/[Delete] buttons when viewing messages instead of typing commands manually.

Changes

Message List View (Mailbox.java)

• Message IDs now render as clickable components that execute /m open <ID> on click
• Added hover tooltip: "Click to open message"
• Preserved existing formatting (bold for unread, 📎 attachment indicator)

Message Detail View (Message.java)

• Added action button row after message content:
  • Green [Archive] button (hidden if already archived) → /m archive <ID>
  • Red [Delete] button (always visible) → /m delete <ID>
• Both buttons include hover tooltips explaining their function

Implementation

Uses Spigot BungeeCord Chat API (TextComponent, ClickEvent, HoverEvent) to create interactive text components:

TextComponent idComponent = new TextComponent("ID: " + message.getID());
idComponent.setClickEvent(new ClickEvent(ClickEvent.Action.RUN_COMMAND, "/m open " + message.getID()));
idComponent.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT, 
    new ComponentBuilder("Click to open message").create()));

All existing commands remain functional. Test coverage added in MessageInteractivityTest.java.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
