Fix 28 issues from deep audit and UI audit + redesign changes

Deep audit (issues 2-14):
- Add missing WCSession handlers for applicationContext and userInfo
- Fix BoundedFIFOQueue race condition with serial dispatch queue
- Fix timer race condition with main thread guarantee
- Fix watch pause state divergence — phone is now source of truth
- Fix wrong notification posted on logout (createdNewWorkout → userLoggedOut)
- Fix POST status check to accept any 2xx (was exact match)
- Fix @StateObject → @ObservedObject for injected viewModel
- Add pull-to-refresh to CompletedWorkoutsView
- Fix typos: RefreshUserInfoFetcable, defualtPackageModle
- Replace string concatenation with interpolation
- Replace 6 @StateObject with @ObservedObject for BridgeModule.shared
- Replace 7 hardcoded AVPlayer URLs with BaseURLs.currentBaseURL

UI audit (issues 1-15):
- Fix GeometryReader eating VStack space — replaced with .overlay
- Fix refreshable continuation resuming before fetch completes
- Remove duplicate @State workouts — derive from DataStore
- Decouple leaf views from BridgeModule (pass discrete values)
- Convert selectedIds from Array to Set for O(1) lookups
- Extract .sorted() from var body into computed properties
- Move search filter out of ForEach render loop
- Replace import SwiftUI with import Combine in non-UI classes
- Mark all @State properties private
- Extract L/R exercise auto-add logic to WorkoutViewModel
- Use enumerated() instead of .indices in ForEach
- Make AddSupersetView frame flexible instead of fixed 300pt
- Hoist Set construction out of per-exercise filter loop
- Move ViewModel network fetch from init to load()
