Startup local rescanning is caused by “Rescan now” shying away in a corner

Usability issues:

• Startup checking is not really necessary https://github.com/xiaoyifang/goldendict-ng/issues/504
• The tab is very loooong and may grow in the future, new tabs are maybe invisible unless the user has a giant screen.
  • or turn it to vertical
• Add a new dict to while adding files when a path is already in "Files", the user needs to open the dialog then close.
• Editing other “somewhat dictionaries” like “Programs” doesn't really need to "rescan" at all
• Cannot open Edit Groups dialog directly.
• There is no "rescan now" button in "Sound Dir" tab.
• Both The opening and "Ok" button of this dialog carries lots of responsibilities

How about[^1]

• Split them into different dialogs
• Change the modality of "Inspect dictionaries" and "Manage groups" dialog, so that "Edit local files", "Inspect dictionaries" and "Manage groups" can be opened in parallel. (Maybe a bad idea.)
• Remove startup scan
• Automatic "Rescan now" in the “local dictionary” dialog only
• Add a quick "Rescan/Reindex now" in menu

Outcome

[^1]: I am pretty aware of the cost of implementing this, this is yet another idea. 😅

• Startup checking is not really necessary boost startup speed  #504

the startup checking based on the following assumption that the dictionaries may have changed before the gd-ng start. Eg, add a new dictionary in the monitored dictionary path.

Without the startup checking , the gd-ng will lost the chance to reflect the new changes in the dictionary.

groups depends on dictionaries . As long as the dictionaries do not change during the above operation .this should be ok.

Sound ok,
But with the startup checking , a quick "Rescan/Reindex now" in menu may never get the chance to run
