[UI] – Implement terminal-wide flight scheduling instead of gate-specific assignment

:placard: UI – Implement terminal-wide flight scheduling instead of gate-specific assignment

:bullseye: What is your suggestion?
Introduce a terminal-based scheduling option within the airport flight planner.

:hammer_and_wrench: How would it work in the game?
Instead of locking each incoming flight contract strictly to a single designated gate, players should have the choice to assign a contract to an entire terminal zone or concourse. The game AI would then automatically route the arriving aircraft to the first available compatible gate within that specified terminal.

:balance_scale: Why is this a good idea?
• Enhanced operational flexibility: Reduces micro-management headaches by stopping cascading schedule delays when a previous aircraft overstays at a specifically assigned gate.
• Realistic airport management: Mirrors real-world aviation hubs where airlines occupy entire terminal blocks and dynamically dispatch planes to open gates.
• Improved user experience: Simplifies scheduling for large-scale airports, making the contract management interface cleaner and easier to scale.
