fix(channels): add ok checks for type assertions in toChannelHashes

Two type assertions in toChannelHashes could panic when channel config values had unexpected types from JSON unmarshal: 1) value[enabled].(bool) panics if the key is missing or not a bool 2) vv.(map[string]string) panics when JSON unmarshal produces map[string]any. Add ok checks to safely handle both cases.
