Matthieu MALVACHE 1306ce56f8 feat(config): Add runtime environment variables for Docker support
Enable post-build configuration by reading env vars at request time
instead of build time. This allows Docker containers to be configured
without rebuilding the image.

- Add /api/config endpoint for runtime config
- Add useConfig hook with caching
- Update login page with proper loading/error states
- Add i18n translations for config errors
- Maintain backwards compatibility with NEXT_PUBLIC_* vars

Getting Started

# Install dependencies
npm install

# Run development server
npm run dev

Open http://localhost:3000 and connect to your JMAP server.

Configuration

Create a .env.local file:

APP_NAME=Your Webmail
JMAP_SERVER_URL=https://your-jmap-server.com

Runtime vs Build-time Configuration

Variable Type Description
APP_NAME Runtime App name displayed in the UI
JMAP_SERVER_URL Runtime JMAP server URL (required)
NEXT_PUBLIC_APP_NAME Build-time Legacy fallback for app name
NEXT_PUBLIC_JMAP_SERVER_URL Build-time Legacy fallback for server URL

Runtime variables are read at request time, enabling post-build configuration (ideal for Docker).

Build-time variables are baked into the bundle and require a rebuild to change.
