feat(net): D.2b-B B-Wire — PlayerDescription delivers player properties to ClientObject

Add optional Func<uint>? playerGuid parameter (last in WireAll signature so all
existing callers compile unchanged). When provided, the PD handler calls
items.UpsertProperties(playerGuid(), p.Value.Properties) immediately after the
null-guard, landing EncumbranceVal (PropertyInt 5) and other player stats into the
player ClientObject. Upsert (create-if-absent) handles PD arriving before the
player's CreateObject. Retires AP-48/AP-49 divergence rows (wired in Task 16).
