Fix showing live tv programs on home page (#1504)

## Description
Fixes the inconsistent live tv programs shown on the home page by using
a different API endpoint & filtering.

Also some UI fixes:
- Use the "Watch live" string consistently for the row instead of it
sometimes switching to "Live TV"
- Adjust the "Ends at" in the home page header to show the actual end
time
- Show the channel name in "quick details"
- Show season & episode number, if applicable, in "quick details"

### Related issues

### Testing

## Screenshots
N/A, just UI fixes, nothing new

## AI or LLM usage
