Implement deeplink, creating pastes, log deduplication

Summary:
This diff implements the remaining features in the logs plugin:

- deeplinking
- merging duplicate rows

The logs plugin source code has now been reduced from originally `935` to `285` LoC. All optimisation code has been removed from the plugin:

* debouncing data processing
* pre-rendering (and storing!) all rows

Finally applied some further styling tweaks and applied some renames to DataTable / DataSource + types finetuning. Some more will follow.
Fixed a emotion warning in unit tests which was pretty annoying.
