[Minor] Migrate lua_maps_expressions.lua from tableshape to lua_shape

Replace tableshape with lua_shape for maps expressions schema:
- Convert ts.shape to T.table
- Convert ts.array_of to T.array
- Keep reference to lua_maps.map_schema (will be migrated separately)

No functional changes, luacheck passes.
