Extract GameSettingsState and tweak popup layout

The settings model now separates generic settings from game‑specific
fields by
introducing `GameSettingsState`. All game‑related fields are moved into
this
struct and `SettingsState` now holds a `game_settings` field.
Initialization in
`GameStates::new` is updated accordingly. The UI popup is rendered
directly
with added padding and a resized rectangle, and the unused `popup_area`
variable is removed.
