Fix authentication state hydration mismatch (#433) 
## Summary
- Fixed avatar showing anonymous for several seconds on page load
- Eliminated hydration mismatch for authentication state
- Header now shows correct user state immediately

## Root Cause
AccountStateInitializer was running client-side in useEffect AFTER
hydration, causing:
1. Server renders anonymous state
2. Client hydrates with anonymous state
3. useEffect runs and updates state (causing the flash)

## Solution
- Read auth cookies server-side in layout.tsx
- Pass initial auth data as props to AccountStateInitializer
- Initialize Valtio state synchronously before first render
- Client-side cookie reading only as fallback

## Changes
- Added server-side cookie parsing in layout.tsx
- Modified AccountStateInitializer to accept initial auth data props
- Made Header component reactive with useSnapshot from Valtio
- State initialization happens synchronously, preventing the flash

## Test plan
- [x] Avatar renders correctly on first load
- [x] No anonymous avatar flash when logged in
- [x] Login/logout still works properly
- [x] State updates are reactive in the header
