Delete the standalone ZB.MOM.WW.LmxProxy solution and loose adapter
stubs under deprecated/, plus the lone LmxProxy mention in
deprecated/windev.md. The protocol was never wired into the active
codebase and the runtime artifact has been removed from the cluster.
LmxProxy is no longer needed. Moved the entire lmxproxy/ workspace, DCL
adapter files, and related docs to deprecated/. Removed LmxProxy registration
from DataConnectionFactory, project reference from DCL, protocol option from
UI, and cleaned up all requirement docs.
