Enhance WebSocket connection management and signer implementation

- Added a pong handler to extend the read deadline upon receiving PONG messages in WebSocket connections, improving connection stability.
- Updated the signer implementation to serialize the x-only public key to 32 bytes, ensuring compatibility with the internal format.
- Refactored tests to utilize MustNew() for signer initialization, enhancing error handling during key generation.
- Bumped version to v0.25.1 to reflect these updates.
