On history react, when the initial screen has been loaded, no default pathname is selected. This PR adds logic for selecting default pathname and getting the diff for that pathname.
Also, add some other small changes, the notable ones are:
- Refactor some type naming and file structure related to the history file tree
- Refactor file tree selectable hooks (merge selectable context provider into the main provider)
- prevent clicking on the same file tree item by checking the current pathname before invoking the handler function

This new history file tree is mostly copied from the editor file tree, with some of the features stripped away:
1. Remove multiple selections
2. Remove drag and drop ability
3. Remove the ability to rename files & folders
4. No more right-click hijacking (context menu)
5. No more triple dots menu on a file tree item shown
6. No file references, since history doesn't have the data to differentiate between real files and linked file
7. etc (some other small changes that are not too important to be listed)
Other notable changes:
1. Simplify the selectable provider (the only context provider being copied from react file tree)
2. Convert to typescript
