-- Fix NULL room paint columns
--
-- Some legacy/imported rooms have NULL in paper_wall / paper_floor / paper_landscape.
-- The server compares these with .equals("0.0") on room entry, which throws a
-- NullPointerException (RoomManager.openRoom) and prevents the room from loading.
-- This normalizes existing NULL values and re-enforces the NOT NULL DEFAULT '0.0'
-- constraint so it cannot happen again.
