Use Jellyfin global styles

[CollinHeist]

It appears global styles (watched_style and unwatched_style) are being ignored for Jellyfin - this needs to be fixed. The issue seems to be here:

TitleCardMaker/modules/Show.py

Lines 107 to 110 in 27242e1

	if self.media_server == 'emby':
	self.style_set = copy(preferences.emby_style_set)
	elif self.media_server == 'plex':
	self.style_set = copy(preferences.plex_style_set)

There needs to be a copy of the global jellyfin style set object.
