fix(artplayer): manage Hls instance and centralize player teardown

Add a dedicated hls field and a destroyPlayer() helper to ensure Hls
instances are properly destroyed when the component is torn down or
re-initialized. Replace inline Hls creation with a guarded pattern that
destroys any existing hls before creating a new one, preventing leaks or
duplicate attachments. Use destroyPlayer() from ngOnDestroy and when the
channel input changes to centralize teardown logic and keep lifecycle
handling consistent.
