Add onscreen keyboard controls for terminal interaction

[aminzabardast]

Introduce onscreen buttons for CTRL, ESC, UP, DOWN, LEFT, RIGHT, and TAB key simulations, enhancing user interaction with the terminal. Refactor existing code to improve functionality and styling of these controls. #557

The interface is simple and resembles the Options section that already exists. I'll add a better interface but that is just UI change. This is functional now. #557

• The variable 'crtlFlag' appears to be misspelled; consider renaming it to 'ctrlFlag' for clarity and consistency.

let crtlFlag = false; // This indicates whether the CTRL key is pressed or not

src/client/wetty/term.ts:207

• The global declaration for 'toggleCTRL' expects a parameter (KeyboardEvent) but the implementation does not take any; update the declaration to 'toggleCTRL?: () => void;' to match the implementation.

toggleCTRL? : (event: KeyboardEvent) => void;

@butlerx The UI is basic but functional. I'll work on a better interface after the functionality is settled.
