Initial Scan/Rescan at startup has no progress bar in UI

[nstephenh]

Describe your suggested feature

When komga starts, the console is full of log messages checking existing series. There is no indicator in the UI (or console) that this scan is in progress or any estimate as to how long it will take. Some indicator on the UI and an estimate of time remaining would be very useful.
Example of the messages I am referring to:

Scan is usually only a few seconds, unless you modified thousands of files.

It depends, on low end hardware the scan can be pretty long even when adding a few hundred files. Especially if some files were renamed or a series was renamed and it is trying to restore the files, it can take a long time.
