refactor(gui): replace verbose key matching with egui native methods (#60)

Browse Source 
Replaced the large match blocks in `chord_from_event` and `parse_chord`
with `egui::Key::name()` and `egui::Key::from_name()`. This drastically
reduces boilerplate code while maintaining the existing behavior that
strictly allows only single-character alphanumeric keys and 'F' keys for
chords.
