Rename GameStates to States and adjust keybindings

Replace the old `GameStates` struct with a new `states` module, rename
the
field in `App` to `states`, and update construction to pass CLI args.
Remove the now‑unused `game_states.rs` file and adjust imports
accordingly.
Update keybinding definitions: change the wildcard symbol to "[All]" and
simplify the wildcard detection logic by dropping the modifiers check.
