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

Header image for hensei-web

hensei-web

hensei-web is the frontend for granblue.team, an app for saving and sharing teams for Granblue Fantasy.

Getting Started

First, you have to set up your environment file. You should start with .env.sample, but here are some gotchas:

App URLs

Don't add a trailing slash to these URLs! The API will run on port 3000 by default, but make sure to change these to match your instance of the API.

NEXT_PUBLIC_SIERO_API_URL='http://127.0.0.1:3000/api/v1'
NEXT_PUBLIC_SIERO_OAUTH_URL='http://127.0.0.1:3000/oauth'

Asset URLs

Next.js serves all assets out of the /public directory. In development we utilize this for all assets, but in production, you will want to host these images on a cloud storage provider like Amazon S3. Once you have that set up and you're running in a production environment, change this to the full bucket URL.

NEXT_PUBLIC_SIERO_IMG_URL='/images'

Dependencies

Once your .env is all set up, install all dependencies:

npm install
# or
yarn install

Then, run the development server with:

npm run dev
# or
yarn dev

Assets

The hensei-api repository has tasks that will help you get assets, although some were crafted or renamed by hand. The front-end expects this folder structure inside of the images folder:

root
├─ accessory-grid/
├─ accessory-square/
├─ awakening/
├─ ax/
├─ character-main/
├─ character-grid/
├─ character-square/

├─ jobs/
├─ job-icons/
├─ job-portraits/
