- didReceiveIncomingPush: normalise payload.dictionaryPayload ([AnyHashable:Any])
to [String:Any] before storing/using (the reported build error at :121).
- CXProviderConfiguration(localizedName:) instead of the no-arg init (available on
all deployment targets, avoids an availability edge).
- Make two 'calls[uuid] ?? [:]' bindings explicitly [String:Any] to avoid empty-
literal inference ambiguity.
