📄 Description

Newer Bitwarden client versions (browser extension v2026.2.0+) send folderId: "" instead of folderId: null when "No folder" is selected. This causes the folder validation at ciphers.rs:451 to attempt a database lookup with an empty string, which naturally fails and returns "Invalid folder" — preventing users from saving credentials entirely.

As identified by @stefan0xC in the issue thread, this is because the Option<FolderId> deserialization treats "" as Some(FolderId("")) rather than None, so the validation code tries to look up a folder with an empty UUID.

This PR normalizes empty folderId values to None at all three places where folder validation occurs:

update_cipher_from_data (create/update cipher)
put_cipher_partial (update cipher details)
move_cipher_selected (move ciphers to folder)

The normalization uses Option::filter to convert Some(FolderId("")) → None before validation, and the normalized value is also passed to move_to_folder so the downstream logic is consistent.

Fixes #6962
