What happened?

I am noticing some inconsistency with the way series numbers are displayed. For numbers under 10, sometimes they have a leading zero and sometimes they don't:

I think this comes from an inconistency with how they are written in the folder name or meta tags. Sometime they may have leading zero, and sometimes not:

00.5
0.5
01.5
1.5

It can also be because people want folder names to sort alphabetically for a book series, especially if there are more than 10 books:

e.g. ...
/Author Name/Series Name/Vol 08.0 - Book Title
/Author Name/Series Name/Vol 08.5 - Book Title (Novella)
/Author Name/Series Name/Vol 09.0 - Book Title
/Author Name/Series Name/Vol 10.0 - Book Title
/Author Name/Series Name/Vol 11.0 - Book Title
/Author Name/Series Name/Vol 11.5 - Book Title (Novella)
etc.

I am not sure whether this is happening in the backend server, or in the web ui.

What did you expect to happen?

The metadata scanner should strip any leading or trailing zeros from the series number as files are scanned. So the above would be converted to this:

#8 - Book Title
#8.5 - Book Title (Novella)
#9 - Book Title
#10 - Book Title
#11 - Book Title
#11.5 - Book Title (Novella)

Obviously, numbers under 1 would still have leading zero, and #0 is also allowed. These are all permitted:

#0
#0.5
#0.05
#0.6
#1
#1.5
#10
#11.5
etc.

Steps to reproduce the issue

1Import some media with following folder names:

/Vol 05.5 - Book Title
/Vol 6.5 - Book Title

Audiobookshelf version

2.30.0
