fix(timer): animate the dial at most one revolution

[Xitee1]

Summary

• On launch the dial animation started at the 15-minute default and tweened to the persisted preset in 360 ms. With a preset of several hours, the ring visibly spun multiple rounds very fast.
• If the target is more than 60 minutes away, the animated value now snaps to one revolution short of the target and animates only the last round.
• Distances below 60 minutes animate as before. The same cap applies when the ring jumps back to a multi-hour preset after the timer ends.

Fixes #55

Test plan

• ./gradlew :feature:timer:compileDebugKotlin :feature:timer:lintDebug
• Set a preset above 1 h, restart the app and check the dial animates at most one round
