Fully reverted sidebar, files_tab, totp_tab, server_dialog to v1.8.10
base. Removed all entry_undo bindings that broke Ctrl+V paste globally.
Only alias editing feature preserved (editable alias + rename support).

crashed. Replaced with custom entry_undo.py that tracks history manually
and binds Ctrl+Z/Ctrl+Y (+ Russian layout support).
