Improve the Data panel with type-specific detail pages and nested-layer support (#4070)

* Improve the Data panel with more type-specific detail pages

* Add network_path to SetDisplayName so renames target any network depth

* Track nested layers via full editor:layer paths and rename parent_layer to path_of_subgraph

* Polish the data panel NodeId leaf page with an editable name field

* Make lock and visibility toggles work for layers in nested subgraphs

* Fix formatting

* Fix connected_to_output running in the wrong network for nested-layer toggles
