Misc Fixes (#2155)

* Fixed default token key not being long enough and Kavita auto-generating

* When scheduling nightly backup job, make it run at 2am to ensure everything else has ran.

* Made the overlay system work better on mobile. In order to do this, had to implement my own copy button.

* Tweaked the code to ensure we clear the selection doing anything and clicking off the overlay clears more reliably.

* Cleaned up the overlay code

* Added the ability to view the series that a rating is representing. Requires Kavita+ deployment.

* When calculating overall average rating of server, if only review is yours, don't include it.

When calculating overall average rating of server, scale to percentage (* 20) to match all other rating scales.

* Fixed side nav on mobile without donate link not fully covering the height of the screen

* Only trigger the task conversion warning on Media screen if you've touched the appropriate control.

* Fixed a bug where bookmark directory wasn't able to be changed.

* Fixed a bug where see More wouldn't show if there were just characters due to missing that check.

* Fixed a typo in documentation

* If a chapter has a range 1-6 and is fully read, when calculating highest chapter for Scrobbling, use the 6.
