228 refactor graphics::window into lvgl component

[AlixANNERAUD]

This pull request refactors the codebase to consistently use the new OwnedWindow abstraction in place of the previous Window type across multiple modules. It also modernizes control flow by adopting Rust's let-chaining (if ... && let ...) and improves code readability by simplifying match and event handling patterns. The changes enhance maintainability, safety, and consistency in UI window management and event processing.

Refactoring to OwnedWindow abstraction:

• Replaced usage of the Window type with OwnedWindow in the FileManager, Settings, Desk, and Login structs, updating all associated window method calls to use as_object_mutable() or as_mut() as appropriate. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19]

Modernizing control flow and event handling:

• Adopted Rust's let-chaining (if ... && let ...) for more concise and readable conditional logic in functions like split_host_port and render_cpuinfo_text. [1] [2]
• Refactored match arms and event handlers to use guard patterns, reducing nesting and improving clarity in event-driven code, especially in the Desk and screen_event_handler implementations. [1] [2] [3] [4] [5]

Code cleanup and minor improvements:

• Simplified match expressions and removed unnecessary nesting in command dispatch and event handling logic.
• Reorganized imports and updated usages to align with the new abstractions and code structure. [1] [2]

These changes collectively improve code consistency, readability, and future maintainability by unifying window management and adopting modern Rust idioms.
