[Fix, Test] (clientfb, MG_Pipe): pass the level a texture respecify redefines - every per-level glTexImage*D and glGenerateMipmap grow took the applier's whole-resource arm and dropped the texture's every pending upload, including a level the applier had accepted at an earlier verb with the client's dirty flag already clear, so L0; draw(other); L1; draw(T) read a black level 0 on the handle arm (final review C-1); the storage entry points now state the scope (one level, a chain cut, the whole resource), the emitter builds wire's MGPRespecifiedLevel with the drain's packed target, a per-level call is never deduped on the descriptor, and the applier drops a named level whether or not the descriptor moved
