Fix request header removal that was causing zstd compressed response when we wanted plain text.

Allows Paskia to authenticate the user to a client site.
- User friendly client registration flow on the admin app
- Redirect-based authentication flow (per spec)
- Backchannel logout both ways to keep sessions synchronized
- Groups integrated with Paskia's permission system
- Adds email, preferred username and telephone fields on user profile
- All new user basic info layout to show the new information, better looks
- API and DB structures redesigned
- Various unrelated fixes to theming and layout

 For a real deployment, configure Paskia with your domain name (rp-id). This enables SSO setup for that domain and any subdomains.

+### Optional: Dedicated Authentication Site
+
+By default, Paskia serves login dialogs and admin interface at the `/auth/` path on each protected site. For a cleaner setup, you can use a dedicated authentication subdomain instead. We assume you have your DNS setup for that domain or a wildcard of all subdomains to current machine.
+
+Configure Paskia with the authentication host:
+
+```fish
+paskia --rp-id example.com --auth-host=auth.example.com --save
+```
+
+Add a Caddy configuration for the authentication domain:
+
+```caddyfile
+auth.example.com {
+    reverse_proxy :4401
+}
+```
+
+Now all authentication happens at `auth.example.com` instead of `/auth/` paths on your apps. No other changes are needed. Your existing protected sites continue to work as before but they just forward to the dedicated site for user profile and other such functionality.

+# OIDC Provider Implementation
+
+OpenID Connect 1.0 provider enabling third-party apps to authenticate users via passkey. Also supports native cookie-based authentication.
+
+## Data Models
+
+**User** — Added: `email`, `preferred_username`
+
+**Session** — Added: `client_uuid` (None = native, set = OIDC)
+- `key: bytes` — hashed DB key, never stored raw
+- `secret` → `hash_secret("session", secret)` → DB lookup
+- OIDC `sid` → `base64url.encode(hash_secret("oidc", session.key))`
+
+**OIDClient** — `uuid, client_secret_hash, name, redirect_uris`
+
+## Auth Codes (In-Memory Only)
+
+60-second lifetime, auto-cleaned:
+
+```python
+from paskia.authcode import AuthCode, OIDC, codes
+
+class AuthCode(msgspec.Struct):
+    session_key: str       # Session DB key
+    created: datetime
+    oidc: OIDC | None      # Only for OIDC mode
+
+class OIDC(msgspec.Struct):
+    redirect_uri, scope, nonce, code_challenge, code_challenge_method: str
+```
+
+Usage: `code = authcode.store(AuthCode(...))` → later `codes.pop(code, None)`
+
+## Authorization Flows
+
+### OIDC (Authorization Code)
+
+1. `GET /auth/restricted/oidc?client_id=UUID&redirect_uri=...&scope=openid&nonce=...&code_challenge=...`
+2. Frontend → WebSocket: `/auth/ws/authenticate?client_id=...&redirect_uri=...&...`
+3. Validate client/redirect_uri, authenticate via passkey
+4. `db.oidc_login()` → `(secret, session_key)`
+5. Create `AuthCode(session_key, oidc=OIDC(...))` → code
+6. Return: `{"redirect_url": "{redirect_uri}?code={code}&state={state}"}`
+7. Client exchanges code at `/auth/oidc/token` with `code_verifier` (PKCE S256)
+
+**Token:** `access_token, id_token, refresh_token={secret}, expires_in=3600`
+
+**ID token:** `sub, sid (base64url), name, preferred_username, email, groups`
+
+### Native (Cookie)
+
+1. WebSocket: `/auth/ws/authenticate` (no OIDC params)
+2. Authenticate via passkey
+3. `db.login()` → secret
+4. Create `AuthCode(session_key=secret, oidc=None)` → exchange_code
+5. Return: `{"user": "UUID", "exchange_code": "..."}`
+6. `POST /auth/api/exchange` with code → sets cookie
+
+## Refresh & Logout
+
+**Refresh:** `POST /auth/oidc/token` with `grant_type=refresh_token&refresh_token={secret}&client_id=...&client_secret=...`
+- Looks up session, validates client match
+- Extends expiry +24h (sliding window)
+- Returns new tokens with same `sid`
+
+**Back-channel logout:** `POST /auth/oidc/backchannel-logout` with `logout_token={jwt}`
+- Verify signature, extract `sid` or `sub`
+- Delete matched sessions
+- Return 200 OK
+
+Discovery: `backchannel_logout_supported: true`
+
+## Endpoints
+
+- `GET /.well-known/openid-configuration` — Discovery
+- `GET /auth/oidc/keys` — Keys (EdDSA)
+- `POST /auth/oidc/token` — Exchange/refresh
+- `GET /auth/oidc/userinfo` — User (bearer token)
+- `POST /auth/oidc/backchannel-logout` — Logout
+- `POST /auth/api/exchange` — Native auth code → cookie

+"""Run Vite development server for Vue app and FastAPI backend with auto-reload."""
-
-This script is only available when running from the git repository source,
-not from the installed package. It starts both the Vite frontend dev server
-and the Paskia backend with auto-reload enabled.
-
-Usage:
-    uv run scripts/devserver.py [-l host:port] [options...]
-
-The optional -l/--listen argument sets where the Vite frontend listens.
-All other options are forwarded to `paskia`.
-Backend always listens on localhost:4402.
-
-Environment:
-    PASKIA_FRONTEND_URL    Set by this script for the backend to know where Vite is.
-    PASKIA_BACKEND_URL     Set by this script for Vite to know where to proxy API calls.
-    PASKIA_SITE_URL        User-facing URL for reset links (Caddy HTTPS or Vite HTTP).
-
-Options:
-    --caddy         Run Caddy as HTTPS proxy on port 443 (requires sudo)
-    --rp-id HOST    Relying Party ID (used as hostname for Caddy)
-    --origin URL    Allowed origin(s), passed to backend
-    --auth-host H   Dedicated auth host, passed to backend
