fix: correct key binding handling and update quit message in scoreboard TUI

**Changed:**

- Fixed key binding handling by replacing "ctrl-c" with "ctrl+c" in the key event switch to match the correct input string
- Updated the on-screen instructions from "q/ctrl-c quit · r poll now" to "q/ctrl-c quit · r reload" for clarity in the scoreboard TUI
