Feature request: Support KP2A_URL_# attributes when accessing KyPass from other apps

[aaaskew]

The problem
Web sites now have different FQDNs for their sign-in pages and their home pages now that they are are using OAuth2/OpenID Connect, etc for authenticaion. So you would want to put https://www.company.com/myaccount in the KeePass URL field but the username and password need to be filled in a web page served by https://signin.company.com/

What can be improved?
When other apps open KyPass to find the password for their URL, the list of entries presented should be filtered on URL field but also the KP2A_URL and KP2A_URL_1, KP2A_URL_2, ..., KP2A_URL_# fields. Using a filter like {URL}.* || {KP2A_URL}.* || {KP2A_URL_1}.* || ...

More information
These fields are used by other KeePass programs, like KeePassXC, to store sign-in URLs which might not be the same as the home page URL for better web browser integration. Among the KeePass managers supporting this feature are Keepass2Android, KeePassXC, KeeWeb, and possibly others.

For example for a Microsoft account:
URL: https://mail.live.com/
KP2A_URL: https://login.live.com/
KP2A_URL_1: https://login.microsoftonline.com/
KP2A_URL_2: https://account.microsoft.com/

This way the Microsoft account entry can be presented when signing in through any of these web pages.
