The apiUrl configured on the Config page was lost when the webview
navigated away to localhost and back. Now it's included in the return
URL as ?desktop=1&apiUrl=...&token=...
SPA navigates to 127.0.0.1:18901/oidc/start, passing ret URL.
Go opens browser, waits for callback, saves token, returns HTML with
<meta refresh> back to Wails app with ?desktop=1&token=TOKEN.
main.ts extracts token from URL on reload.
SPA fetches /oidc/open (returns session ID immediately), then polls
/oidc/result every 500ms. Go server opens browser in a goroutine.
Webview never leaves the Wails origin. Token is saved to keychain and
returned through the poll response.
The webview navigates to http://127.0.0.1:18901/oidc/open?apiUrl=...
The Go server opens the system browser to Authentik, waits for callback,
exchanges code for token, saves to keychain, then redirects the webview
back with ?desktop=1&token=TOKEN. main.ts extracts the token from URL.
The local HTTP server approach (fetch to 127.0.0.1) doesn't work in the
Wails webview. Simplify: use window.open() to launch OIDC in the real
browser. After authentication, the callback page at the server shows the
token. User copies and pastes into the Token tab.
Also fix: SetSize before app.Run() crashes with nil pointer — use
WebviewWindowOptions width/height directly from restored state.
- Server: /oidc-callback HTML page exchanges Authentik code for token,
displays it for user to copy into the desktop app's Token tab
- oidc.ts: desktop mode uses apiUrl+/oidc-callback as redirect URI,
encodes PKCE verifier in state parameter
- Config.svelte: add Server URL field to OIDC tab for desktop UX
- Caddy: add /oidc-callback to enroll bypass (no Authentik gate)
- App: favicon.png as system tray icon, window title 'Oikos'
- web/index.html: title 'Oikos'
