Bookmarking Pages within the Reader (#469)

# Added
- Added: Added the ability to bookmark certain pages within the manga (image) reader and later download them from the series context menu. 

# Fixed
- Fixed: Fixed an issue where after adding a new folder to an existing library, a scan wouldn't be kicked off
- Fixed: In some cases, after clicking the background of a modal, the modal would close, but state wouldn't be handled as if cancel was pushed

# Changed
- Changed: Admin contextual actions on cards will now be separated by a line to help differentiate. 
- Changed: Performance enhancement on an API used before reading

# Dev
- Bumped dependencies to latest versions

=============================================
* Bumped versions of dependencies and refactored bookmark to progress.

* Refactored method names in UI from bookmark to progress to prepare for new bookmark entity

* Basic code is done, user can now bookmark a page (currently image reader only).

* Comments and pipes

* Some accessibility for new bookmark button

* Fixed up the APIs to work correctly, added a new modal to quickly explore bookmarks (not implemented, not final).

* Cleanup on the UI side to get the modal to look decent

* Added dismissed handlers for modals where appropriate

* Refactored UI to only show number of bookmarks across files to simplify delivery. Admin actionables are now separated by hr vs non-admin actions.

* Basic API implemented, now to implement the ability to actually extract files.

* Implemented the ability to download bookmarks.

* Fixed a bug where adding a new folder to an existing library would not trigger a scan library task.

* Fixed an issue that could cause bookmarked pages to get copied out of order.

* Added handler from series-card component
