Next_page keybinding fails to trigger pagination/scrolling across views

[generic-user]

Hi there, thanks for maintaining this project! Below is a bug report regarding a pagination issue I encountered.

---

Describe the bug
The next_page action fails to page down or scroll when triggered inside standard list views (such as playlists, library, or liked songs).

To Reproduce
Steps to reproduce the behavior:

1. Open spotatui and navigate to any playlist that exceeds the current viewport height.
2. Press the configured next_page keybinding (default: ctrl-d).
3. See error: The interface remains completely static and does not scroll down.

Expected behavior
The viewport should advance down by a page/block or trigger the next block of API results.

Screenshots
N/A

Desktop (please complete the following information):

• OS: Bazzite Linux (Fedora-based, immutable)
• Terminal: kitty (running Fish shell)
• Version: 0.38.6

Additional context
I performed some isolation debugging to rule out terminal environment factors:

• Verified that ctrl-d registers completely fine inside the application's GUI settings view.
• Reassigned the next_page action to a standard, unmodified alphanumeric key (d) to isolate terminal protocol/modifier interception issues; the action still fails to execute.

Thanks in advance for your time and help!
