feat: major app overhaul — API fixes, glassmorphism UI, health dashboard, notifications

API Integration:
- Fix logHabit: send "date" instead of "completed_at"
- Fix FinanceCategory: "icon" → "emoji" to match API
- Fix task priorities: remove level 4, keep 1-3 matching API
- Fix habit frequencies: map monthly/interval → "custom" for API
- Add token refresh (401 → auto retry with new token)
- Add proper error handling (remove try? in save functions, show errors in UI)
- Add date field to savings transactions
- Add MonthlyPaymentDetail and OverduePayment models
- Fix habit completedToday: compute on client from logs (API doesn't return it)
- Filter habits by day of week on client (daily/weekly/monthly/interval)

Design System (glassmorphism):
- New DesignSystem.swift: Theme colors, GlassCard modifier, GlowIcon, GlowStatCard
- Custom tab bar with per-tab glow colors (VStack layout, not ZStack overlay)
- Deep dark background #06060f across all views
- Glass cards with gradient fill + stroke throughout app
- App icon: glassmorphism style with teal glow

Health Dashboard:
- Compact ReadinessBanner with recommendation text
- 8 metric tiles: sleep, HR, HRV, steps, SpO2, respiratory rate, energy, distance
- Each tile with status indicator (good/ok/bad) and hint text
- Heart rate card (min/avg/max)
- Weekly trends card (averages)
- Recovery score (weighted: 40% sleep, 35% HRV, 25% RHR)
- Tips card with actionable recommendations
- Sleep detail view with hypnogram (step chart of phases)
- Sleep segments timeline from HealthKit (deep/rem/core/awake with exact times)
- Line chart replacing bar chart for weekly data
- Collect respiratory_rate and sleep phases with timestamps from HealthKit
- Background sync every ~30min via BGProcessingTask

Notifications:
- NotificationService for local push notifications
- Morning/evening reminders with native DatePicker (wheel)
- Payment reminders: 5 days, 1 day, and day-of for recurring savings
- Notification settings in Settings tab

UI Fixes:
- Fix color picker overflow: HStack → LazyVGrid 5 columns
- Fix sheet headers: shorter text, proper padding
- Fix task/habit toggle: separate tap zones (checkbox vs edit)
- Fix deprecated onChange syntax for iOS 17+
- Savings overview: real monthly payments and detailed overdues from API
- Settings: timezone as Menu picker, removed Telegram/server notifications sections
- All sheets use .presentationDetents([.large])

Config:
- project.yml: real DEVELOPMENT_TEAM, HealthKit + BackgroundModes capabilities
- Info.plist: BGTaskScheduler + UIBackgroundModes
- Assets.xcassets with AppIcon
- CLAUDE.md project documentation
