New: inventory see mod

The Invsee mod allows players to view other players’ inventories using the /invsee <playername> command. Only players with the invsee privilege (such as administrators or moderators) can modify the target player’s inventory. Players without this privilege can only view it in read-only mode.

This mod is intended for Minetest / Luanti servers and provides a simple tool for server staff to inspect and manage player inventories.
