Externally opened attachments are now lifecycle-managed properly. The temporary files are created with stricter permissions and entirely random names (except for the file extension) to prevent meta data leakage. When the database is closed, the files are overwritten with random data and are also more reliably deleted than before. Changes to the temporary files are monitored and the user is asked if they want to save the changes back to the database (fixes #3130). KeePassXC does not keep a lock on any of the temporary files, resolving long-standing issues with applications such as Adobe Acrobat on Windows (fixes #5950, fixes #5839). Internally, attachments are copied less. The EntryAttachmentsWidget now only references EntryAttachments instead of owning a separate copy (which used to not be cleared properly under certain circumstances).
