Third-party extensions (e.g. Spotify PKCE addons) need three things the current app does not fully provide:
Extension button results – The Go runtime returned { success, result: { message, open_auth_url, … } } while Flutter read message / open_auth_url only on the outer map, so OAuth buttons appeared to do nothing. InvokeAction now merges the extension’s return object onto the top-level JSON (arrays/non-objects still use result).
Flutter – extension_detail_page: unwrap nested result for compatibility, merge setting_updates into saved extension settings (for copyable OAuth URLs), and launchUrl when open_auth_url is set.
Mobile OAuth return – spotiflac://callback?code=…&state=<extension_id> was not handled on Android (manifest + MainActivity) or iOS (AppDelegate open URL + cold-start launchOptions). This wires SetExtensionAuthCodeByID + invokeExtensionAction(..., "completeSpotifyLogin") so PKCE extensions can finish login after the browser redirect.
Extension store HTTP – Add Cache-Control: no-cache on registry and extension package downloads to reduce stale CDN/proxy responses.
Testing: Install a metadata extension that uses PKCE; tap Connect; confirm browser opens, return via spotiflac://callback, and tokens complete without pasting the code manually.
extension InvokeAction JSON was nested under result while the Flutter settings UI only read the top level, so OAuth-related buttons never showed messages or opened the browser. This PR flattens that payload, merges optional setting_updates, launches open_auth_url, adds spotiflac://callback handling on Android and iOS, and sends no-cache on store HTTP fetches. Needed for extensions like SpoitiLists (Spotify Web API + PKCE).
