fix: security hardening — Keychain, no hardcoded creds, safe URLs

Browse Source 
- Add KeychainService for encrypted token storage (auth, refresh, health JWT, API key)
- Remove hardcoded email/password from HealthAPIService, store in Keychain
- Move all tokens from UserDefaults to Keychain
- API key sent via X-API-Key header instead of URL query parameter
- Replace force unwrap URL(string:)! with guard let + throws
- Fix force unwrap Calendar.date() in HealthKitService
- Mark HealthKitService @MainActor for thread-safe @Published
- Use withTaskGroup for parallel habit log fetching in TrackerView
- Check notification permission before scheduling reminders
- Add input validation (title max 200 chars)
- Add privacy policy and terms links in Settings
- Update CLAUDE.md with security section

- **Color pickers:** LazyVGrid 5 columns (not HStack — overflow on small screens)
- **App icon:** Glassmorphism style, Assets.xcassets/AppIcon.appiconset
## Security
- **Keychain** — все токены (auth, refresh, health JWT, API key) хранятся в iOS Keychain через `KeychainService.swift`, не в UserDefaults
- **Health credentials** — email/password для health API хранятся в Keychain, устанавливаются один раз при первом запуске
- **API key** — передаётся в `X-API-Key` header, не в URL query parameter
- **No force unwraps** — URL создаются через guard/optional binding
- **HealthKitService** — помечен `@MainActor` для thread-safe @Published
- **Privacy policy** — ссылки в Settings (pulse.digital-home.site/privacy, /terms)
## Key Design Decisions & Gotchas
- **Buttons in ScrollView/List MUST have `.buttonStyle(.plain)`** — otherwise taps get swallowed
- **Tracker rows:** Separate tap zones — `.onTapGesture` on text area for edit, `Button` with `.buttonStyle(.plain)` for checkbox
