Motivation

• Surface actual bookmark and folder entries in the macro step picker instead of showing "add/remove" commands.
• Ensure selected macro steps resolve to the real bookmark URL or folder path rather than an add/remove action.
• Preserve the user's filter input by passing self.add_filter into the list queries.
• Provide parity for folders by adding explicit support for a f list command.

Description

• Updated src/gui/macro_dialog.rs to call plugin.search(&format!("f list {}", self.add_filter)) for folders and plugin.search(&format!("bm list {}", self.add_filter)) for bookmarks when building the macro action list.
• Added a list_entries helper, LIST_PREFIX handling, and a new f list command in src/plugins/folders.rs so folder list queries return folder paths (not add/remove actions).
• Kept the existing query: resolution logic so when a command action is a query: it is resolved via plugin.search and the resolved action/args are stored in the created MacroStep.
• Passed the current self.add_filter into the new list queries to retain previous filtering behavior.

Testing

• No automated tests were executed for this change.
• Existing unit tests in the repository were not run as part of this patch.
