Display Entities - Холограммы и NPC для Paper и Folia

Changes

• Added clone sub-command, which allows you to easily clone display entities.
• Added insert_line sub-command, which allows you to add a new text line before specified index.
• Added fallback message for missing command usages.
• Increased maximum character length in display name to 48.
• Improved handling error handling of scale sub-command.
• Loading resource-packs now force refreshes all plugin-created text displays around the player. This ensures custom font characters are aligned properly.

New commands may not automatically appear in /display help and usage messages. If that's the case, add entries manually or reset your configuration file to default values.

Alternatively, you can remove just the messages.command_usages section along with messages.command.display.help.contents list, and let plugin re-generate them upon next reload.
