[UI] - Add Option to Hide List of fixed airports on the right

:bullseye: What is your suggestion?
Add a simple way to hide the right-side airport list on the world map screen, so players can choose whether to show or hide it.

:hammer_and_wrench: How would it work in the game?
Either one of these two ways would work great:

1. Add a toggle in Settings to turn the right-side airport list on/off.

​2. Add a small collapse/expand button directly on the right-side panel in the world map screen. Players can tap it to hide the list, or leave it visible as usual.

:balance_scale: Why is this a good idea?
It gives players full freedom to choose their favorite way to pick airports, without taking away anyone’s existing experience.

​It effectively cuts down on accidental taps, which will only get more common as more playable airports are added in future updates.

​It makes the interface cleaner and gives more space to the world map, making airport selection more immersive and intuitive.

​Having two nearly identical interaction flows creates unnecessary repetition; a hide option streamlines the game without removing any useful functions.

​It’s a small, low-effort change for the dev team but makes a big improvement to daily gameplay comfort and long-term interface scalability.
