[Minor] Migrate lua_aws.lua from tableshape to lua_shape

Replace tableshape with lua_shape for AWS parameter validation:
- Convert ts.shape to T.table
- Replace ts.string + ts['nil'] / fn with T.transform + T.one_of
- Replace ts.map_of(ts.string, ts.string) with open table validation
- Update documentation comments to reflect new schema format

No functional changes, luacheck passes.
