Fix modifier order in keycode string generation

Fix the order in which modifier keys are appended in as_text() and keycode_get_string() to ensure consistent and logical ordering (Ctrl, Alt, Shift, Meta). Refactored keycode_get_string() to use a vector for building the key string, improving readability and maintainability.
