[PS4] Support for external keyboard

[an0n137]

Is your feature request related to a problem? Please describe.

I bought a DOBE PS4 2.4G Remote Controller TP4-018 to make it easier to navigate while watching movies on Switchfin (PS4 version).

However, the remote doesn’t work at all inside the Switchfin app. It only works in the main PS4 menu and in other apps like YouTube.

Additionally, the TP4-018 is not recognized as an extra controller, but rather as an external keyboard. The remote has its own USB dongle that connects via 2.4G Wi-Fi.

Describe the solution you'd like

I would like Switchfin to support external keyboards like the DOBE TP4-018 remote, so that it can be used for navigation and playback control inside the app, similar to how YouTube recognizes and allows full use of the remote.

Describe alternatives you've considered

Currently, the only alternative is to use the PS4 controller itself or navigate with the console interface, which is less convenient.

Additional context

Since YouTube can fully utilize this remote, it seems technically possible for Switchfin to do the same. Adding support would improve usability for users who prefer a dedicated media remote.
