File Created Date (#1434)

* Capture date when Kavita creates a MangaFile so we can show the date on the UI.

* On startup, exit early for migration directory if it's a fresh install and we have migrations to run but no settings stored yet.

* Blur summaries should apply when there isn't any read more collapsable

* Fixed custom theme files not loading.

* Cleaned up the logic for displaying the manga file date
