Phase 3: Real Spotify account integration with zone mapping

- Created SpotifyContext for account management
  * Add/remove Spotify accounts with email and display name
  * Persistent storage to localStorage
  * Automatic account activation when assigned to zone

- Implemented zone-to-account mapping system
  * Each zone can be assigned a Spotify account
  * Multiple zones can share one account
  * Switching between sources preserves account assignment

- Enhanced ZoneCard component:
  * Account selector dropdown when Spotify is selected
  * Display account name/email under zone name
  * Auto-select first account when switching to Spotify
  * Green-tinted account dropdown for visual distinction

- Created SpotifyAccountManager component:
  * Add new Spotify accounts with email and display name
  * List all configured accounts
  * Remove accounts (cleans up zone mappings)
  * Collapsible form for adding new accounts
  * Glassmorphic styling with green accent

- Updated Audio page:
  * New 'Accounts' tab for Spotify account management
  * Accessible alongside Zones, Radio, and Library tabs
  * Smooth tab transitions with animations

- Architecture supports:
  * Real Spotify API integration (ready for OAuth)
  * Multiple accounts simultaneously
  * Spotify Connect per account (one instance per account)
  * Zone grouping with shared account control

- Build: 70 modules, 1.25 MB (345 KB gzipped)
