SluijsensandClaude Haiku 4.5 546b773781 fix(auth): add Vite dev proxy to fix SameSite=Strict cookie on page reload
Chrome 89+ treats http://localhost and https://localhost as different sites
(schemeful same-site). The refreshToken cookie (SameSite=Strict) was not
sent when the Vite dev server (HTTP) made cross-origin fetch calls to the
.NET backend (HTTPS), causing a 401 on every page reload.

Fix: route /api/* through the Vite dev server proxy so all requests stay
same-origin. The cookie is now always sent and auth sessions survive reloads.

- vite.config.ts: proxy /api → https://localhost:7221 (secure:false for dev cert)
- .env.example: document proxy vs direct mode, set default VITE_API_BASE_URL to empty
- config.ts: accept empty string as valid apiBaseUrl alongside full URLs

# Base URL of the SlpModularCms .NET API.

# LOCAL DEV (recommended): leave empty and configure the Vite proxy in
# vite.config.ts. The proxy forwards /api/* to the backend so all requests
# stay same-origin — required for the SameSite=Strict refresh-token cookie.
VITE_API_BASE_URL=
# DIRECT (no proxy): point to the backend URL. CORS must allow this origin
# with credentials, and SameSite may block the cookie on page reload if the
# schemes differ (e.g. http frontend → https backend).
# VITE_API_BASE_URL=https://localhost:7221
