Refactor keys_status.html for improved layout and scrolling behavior

- Removed duplicated padding and simplified CSS for `body`, ensuring proper spacing with 20px padding.
- Adjusted `.container` styles:
  - Removed custom scrollbar styles and overflow-related attributes.
  - Centered the element with `margin: 20px auto`.
- Updated scroll behavior:
  - Changed scroll functions to operate on `window` instead of `.container`.
  - Modified event listeners to use `window` for detecting scroll events.
- Cleaned up redundant or unused styles and improved readability.
