[Bug]: Style file defaults to ".csv" when "*.csv" is used to load multiple style files.

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

Using the "dev" branch of webui I used the --styles-file command line parameter to specify *.csv as the pattern to use to match styles files. Although all the expected files loaded, when I edited any of them the changes were written to a file named .csv rather than styles.csv.``

Steps to reproduce the problem

1. Launch webui with the --styles-file command line parameter set to *.csv
2. Edit & save an existing style
3. Observe that a new file named .csv has been created

What should have happened?

1. Launch webui with the --styles-file command line parameter set to *.csv
2. Edit & save an existing style
3. The new style should have been saved to styles.csv (i.e. the default name for a style)

More broadly, if a wildcard is used to load styles csv files, then we should default to "styles.csv" if there is no CSV present that matches the simplest possible match of the wildcard. That is, if w*.csv is used to load style files starting with w, and w.csv doesn't itself exist, then use styles.csv as the fall-back default.
