Minor improvements

Summary:
Some styling fixes and minor improvements in DataTable, used by network plugin:

- be able to customise the context menu
- be able to customise how entire rows are copied and presented on the clipboard to be able to deviate from the standard JSON
- deeplink handling was made async, this gives the plugin the opportunity to first handle initial setup and rendering before trying to jump somewhere which is a typical use case for deeplinking
