[KEPLR-503] Add Reject bottom button on user interaction required page

[piatoss3612]

Changes

1. useInteractionInfo Hook

   • Fixed issue where unmounting components rejected all requests (e.g., back button, macOS gestures).
   • Separated cleanup for window closure and component unmount to handle requests sequentially.

2. HeaderLayout

   • Updated to accept multiple bottom buttons via an array.
   • Explicitly set button types to prevent accidental form submissions when using onSubmit.

3. Button Left Style

   • Applied transparent when the icon’s fill is none to remove white background.

4. Reject Button Handling

   • Processes the next request if available.
   • If no pending requests:
     • External Interaction: Handled the same as approve.
     • Internal Interaction: Rejects without navigating away, allowing back or home navigation.
     • Unexpected Situations: Redirects to home using replace.
