Embed both Microsoft UEFI CA 2011 and 2023 signed DCS EFI sets and select the 2023 set only when the firmware db trusts the required 2023 third-party CAs. Fall back to the 2011 EFI set when firmware db state cannot be determined, preserving pre-existing compatibility behavior and recording the reason in HKLM diagnostics. Refresh installed ESP modules during PostOOBE repair, keep backups before replacing existing DCS modules, and use the selected EFI set when creating rescue media. Record the selected EFI bootloader resource set and selection reason in HKLM, allow larger firmware db variables on systems with many Secure Boot certificates, and remove diagnostic registry keys on uninstall. Fix MSI SetupDLL COM typelib version constants so unregister targets the current Main and Format COM typelib versions. References: https://github.com/veracrypt/VeraCrypt/issues/1655
