Rewards now live in their own tab

Rewards has its own tab again, sitting in the middle of the bottom navigation between Workouts and Activity. It had been folded into the Activity screen; it is now a full page of its own.

One rule worth knowing: only workouts logged on the actual day they happened count toward your weekly reward streak. If you open the Workouts calendar and fill in a day from last week, it still saves normally and still shows on your calendar, but it just will not count toward that week's reward, since the reward is meant to reflect real day-to-day consistency, not calendar cleanup after the fact.

Days that count show a green ring on the Rewards calendar, so it is always clear at a glance which ones are reward-eligible.
