dopamine-ux 05: selectionClick on recording a set or warmup,
mediumImpact + generated chime (music_theory, pinned tag) on
finish, dialog arrival on the slow motion token, AppDuration /
AppCurve in theme.dart, streak card counts up, all of it
collapsing under the OS reduced-motion flag. One Settings
"Sound" switch silences the chime and the break-end cue
(foreground service included, via a silent channel); haptics
stay. Removes the finished dopamine-ux-05 prompt.

Replaces the dead ColorScheme.fromSeed(Colors.indigo) (declared but
never consumed by any screen/widget) with theme.dart: an explicit
dark ColorScheme plus a real AppStatusColors extension, since this
app genuinely uses success/warning status colors throughout (unlike
dufs-cloud's app). Routes all 10 screen/widget files' ~280 hardcoded
Colors.*/fontSize literals through it. Fixes the two flagged
DESIGN_AUDIT_TODO violations: home_screen's Resume/Start buttons now
use a real 2x horizontal:vertical padding ratio, and rep_circle's
BoxShadow (the one shadow in an otherwise flat dark UI) is removed.
