Auth Email Rework (#1567)

* Hooked up Send to for Series and volumes and fixed a bug where Email Service errors weren't propagating to the UI layer.

When performing actions on series detail, don't disable the button anymore.

* Added send to action to volumes

* Fixed a bug where .kavitaignore wasn't being applied at library root level

* Added a notification for when a device is being sent a file.

* Added a check in forgot password for users that do not have an email set or aren't confirmed.

* Added a new api for change email and moved change password directly into new Account tab (styling and logic needs testing)

* Save approx scroll position like with jump key, but on normal click of card.

* Implemented the ability to change your email address or set one. This requires a 2 step process using a confirmation token. This needs polishing and css.

* Removed an unused directive from codebase

* Fixed up some typos on publicly

* Updated query for Pending Invites to also check if the user account has not logged in at least once.

* Cleaned up the css for validate email change

* Hooked in an indicator to tell user that a user has an unconfirmed email

* Cleaned up code smells
