feat: production-grade Live Activity with type-safe phases, decomposed views, previews, and alert transitions

Browse Source 
- Replace raw string phase model with WorkoutPhase enum (Codable, Sendable, CaseIterable)
  with built-in .capitalized display name and SwiftUI .color per phase
- Decompose WorkoutLiveActivity into reusable view structs: PhasePill, CountdownText,
  WorkoutProgressBar, MusicInfoRow, HeartRateBadge, PhaseIndicatorDot, WorkoutLockScreenView,
  WorkoutSmallView — following CraftingSwift iOS 26 architecture patterns
- Add AlertConfiguration on work/rest/complete phase transitions so Dynamic Island
  expands and lights up at key moments
- Add 13 #Preview blocks across both widgets covering all presentation types:
  lock screen, expanded, compact, minimal — for instant Xcode Canvas feedback
- Add stale state handling (context.isStale shows 'Last updated' indicator)
- MusicLiveActivity: 5 new #Preview blocks for playing/paused/expanded/compact/minimal
