AuthenticatorChooser: all versions and old releases

Features
- #30: Optionally automatically submit the USB security key PIN dialog after a customizable number of characters have been typed, which is more convenient than having to press Enter at the end.
- Enable with the argument --autosubmit-pin-length=5, where 5 is the length of your PIN.
- Thanks @felipecrs for suggesting this.
Fixes
- #36: Change the detection algorithm for the style of FIDO dialog box (23H2 or 25H2) to avoid comparing UI label strings which can collide across multiple dialog boxes in some languages, causing incorrect behavior. Instead, use an automation IDs that happens to have unique values per OS version.
- Thanks @AlanIWBFT for reporting this.
- #44: Force this program to always run as administrator, because the Windows 11 2026-01 Security Update raised the integrity level of the Windows Security dialog box process
- If you had already set this program to autostart when you log in to Windows, that may silently fail now because Windows refuses to show UAC prompts for startup programs. To fix this, run AuthenticatorChooser --autostart-on-logon once more, which converts the registry autorun into a scheduled task.
- Thanks to @Nono-m0le for reporting this, and @AFulgens, @DennisGaida, @felipecrs, @danofnz, @AshtonKnight, and @NETertainer for experimenting with and testing solutions.
