[WIP] Support nested folders on Bitwarden import

[Copilot]

Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.

Original issue description:

Summary

To create a nested folder, give a new folder a name that includes the "parent" folder following by a forward slash (/) delimiter, for example Socials/Forums. You can also rename existing folders in the same way to nest them under other existing folders.

https://bitwarden.com/help/folders/

Fixes #11491.

Try this plan again

I've implemented nested folder support for Bitwarden imports. The solution parses folder names with forward slashes (like "Socials/Forums") and creates the proper hierarchy. For example, "Work/Projects/Client A" now creates a Work group containing a Projects group containing a Client A group. The implementation includes a new test case and maintains backward compatibility with simple folder names. Commit: 5d83fbb

Check your solution again now that you have new instructions and environment

I've reviewed my solution thoroughly with the new instructions and environment:

✅ Build & Tests: Code builds successfully and all tests pass (including my new nested folder test)
✅ Code Formatting: Applied cmake --build . --target format to ensure proper formatting
✅ Internationalization: Ran ./release-tool i18n lupdate to update translation files
✅ Implementation: Correctly parses nested folder paths like "Socials/Forums" and "Work/Projects/Client A", creating proper group hierarchies
✅ Backward Compatibility: Simple folder names continue to work as before
✅ Edge Cases: Handles empty paths, existing groups, and various nesting scenarios

The solution follows KeePassXC patterns and successfully implements the Bitwarden nested folder feature as specified in the issue. Commit: cd22010
