feat: improve hover avatars with smooth animation and 3D elevation

Major improvements to networked hover presence feature:

FIXES:
- Only send hover events when it's YOUR TURN (not all sessions)
  * Check isLocal property of current player before sending hover
  * Prevents all players from broadcasting hover simultaneously

VISUAL ENHANCEMENTS:
- 3D elevation effect with layered shadows for floating appearance
  * Large shadow: 0 8px 20px rgba(0,0,0,0.4)
  * Medium shadow: 0 4px 8px rgba(0,0,0,0.3)
  * Glow effect: 0 0 30px with player color
  * Drop-shadow filter for extra depth
  * 48px avatar size (up from 40px)

SMOOTH ANIMATIONS:
- React-spring for butter-smooth position transitions
  * Tension: 280, Friction: 60, Mass: 1
  * Avatars glide smoothly between cards as mouse moves
  * No jank, feels like remote mouse cursor

- Floating animation with vertical bob
  * 6px up/down motion over 2s
  * Creates illusion of hovering above surface
  * Combined with horizontal spring animation

ARCHITECTURE:
- HoverAvatar component uses fixed positioning
- Card refs stored in Map for position tracking
- Avatar positions calculated from card getBoundingClientRect()
- Rendered outside card wrapper to avoid clipping
- Position updates trigger spring animations automatically

RESULT:
Feels like you're literally watching someone's mouse move over the cards
from across the internet. Smooth, elevated, and visually distinct.
