Add WeFax 24h broadcast timeline and improve start button feedback

Browse Source 
Flash the Start button itself with amber pulse when clicked without a
station selected, and show "Select Station" in the strip status text
right next to the button so the error is immediately visible.

Add a 24-hour timeline bar with broadcast window markers, red UTC time
cursor, and countdown boxes (HRS/MIN/SEC) that tick down to the next
broadcast. Broadcasts show as amber blocks on the timeline track with
imminent/active visual states matching the weather satellite pattern.
