Misc UI Fixes (#1477)

* Tweaked a Migration to log correctly only if something is going to be done.

* Refactored Reading List Controller code into a dedicated service and cleaned up some methods that aren't needed anymore.

* Fixed a bug where adding a new item to a reading list wasn't adding it at the end.

* Fixed an issue where collection page would re-render the same covers on multiple items.

* Fixed a missing margin-top which made the page extras drawer not render correctly and hence unclosable on small screens.

* Added some timeout on manage users screen to give data time to flush.

Added a dedicated token log for account flows, in case url encoding plays a part (but from testing it doesn't).

* Reverted back to building for ES6 instead of es2020 for old Safari 12.5.5 browsers (10MB difference in build size).

* Cleaned up the logic in removing series not found during scan loop.

* Tweaked the timings for Library Watcher to 1 min and reprocess queue every 30 seconds.
