refactor: useKeyboardEvents composable (#9959)

This PR has the following changes

1. Fix tab styles issue caused by adding an additional wrapper for
getting an element ref on `ChatTypeTabs.vue`
2. Refactor `useKeyboardEvents` composable to not require an element
ref. It will use a local abort controller to abort any listener
