Subject: [PATCH] feat(race): show contest display name and human-readable
 countdown

Problem: race notifications showed raw contest IDs (e.g. "2204") and
formatted time as `HH:MM:SS`, which is unreadable for multi-day waits.

Solution: look up `display_name` from cache and use it in the timer
notification. Format countdown as `9d 15h 27m 3s`. Remove redundant
initial log since the timer fires immediately.
