[UI] - Consolidated Fleet View & Model Switcher for Airline Route Contracts

:bullseye: What is your suggestion?
Reorganize the contract/fleet purchase screen by consolidating multiple aircraft variants of the same airline under a single route into one dynamic Airline Fleet Card (or collapsible drawer), rather than displaying separate giant cards for every single aircraft model.

:hammer_and_wrench: How would it work in the game?
​Single Card per Airline: Clicking an airline’s contract offer opens a single consolidated card for that airline on the selected route.

​Model Switcher Tabs: Inside the card, a horizontal tab bar displays available models ( [A359] [A333] [A343] [B77W]).

​Dynamic Viewport: Tapping a model tab updates the central 3D aircraft render preview, collection status (:open_book: Collected / :red_question_mark: Uncollected), stand size requirement, and unlock price dynamically.

​Contextual Action Button:

​If locked: Displays the standard Wollars unlock button (:unlocked: ).

​If unlocked: Displays an [ON / OFF] dispatch toggle, allowing players to enable or disable specific aircraft models from spawning on that route.

:balance_scale: Why is this a good idea?

​Drastically Reduces Clutter: Cuts horizontal card scrolling by up to 75% while keeping the UI clean and responsive.

​Preserves Visual Quality: Maintains full 3D livery previews and collection aesthetics without sacrificing screen space.

​Better Fleet Control: The ON/OFF toggle prevents smaller aircraft variants from hogging large stands when players only want widebodies operating on long-haul routes.

​Economy Intact: Retains the exact same Wollars unlock economy and contract unlocking mechanics.
