♻️(frontend) extract permission checks into reusable hook by media kind

Create hook to encapsulate permission denied/prompted/loading checks
based on media kind, eliminating props drilling and simplifying code.

Returns appropriate permission state for consuming components based on
media type, cleaning up code structure with small enhancement.
