Move acore_string IDs

The IDs start at 11000, imo they should start at the end of the official ones, so after 36000

So if we add new lines inside the core, they can be inserted below 36000, but for anything custom, it's above.
Applies to everything custom

Start by locating the acore_string IDs and the definitions for official and custom strings in the mod-transmog repository. Review every custom ID, confirm the official range ends at 36000, and verify that custom IDs are placed above it without collisions.
