feat: sidebar and new soup layout

[dev-rb]

This PR:

Introduces an app wide sidebar to the left side that contains the navigation links to open certain list views in the active split (or a new split with shift click), actions to access settings, create, command menu, and search, and a wip section for displaying channel updates and recents.

Additionally, the layout of soup is changed so that there is now a bar of filters for that particular list of entities, a search bar, and sort dropdown. There are also "tabs" in the split header for each soup list that applies filters to change the "category" of entities being shown

I also created a new button component that matches the styling of the rest of the changes with the intention that it replaces the button in ui so that we can have consistent styling. However, this depends on what styling we actually want to go with and then making the changes.

Other noteworthy updates:

• Updated the filter system for soup to allow setting "and" and "or" filters which allows the new filters to be applied on top of each other and get entities that match any of the "or" filters.
• Replaces most, if not all, of references to "unified-list" for splits with the appropriate new list view semantics. The default content for a split is now the "inbox".
• Added support for new sort options
• Updated the hotkey system to support attaching hotkeys to a shared and existing command scope.
• Added email attachments to EmailEntity
