Implement portrait generation and retrieval for people in the school system. Added new API endpoints for generating and fetching portraits, including support for avatar and full-body images. Updated the client-side to handle portrait states and display options. Enhanced the person card UI to include tabs for overview and portrait, with appropriate localization strings. Updated solution files to include new test projects. Adjusted server configuration for SwarmUI integration.

+### `GET /api/schools/{id}/people/{personId}/portrait`
+
+Returns a generated PNG when one exists. Query `kind=avatar|full` selects head-and-shoulders or
+full-body. Unknown school is `404` `unknown-school`; unknown person is `404` `unknown-person`;
+missing file is `404` `portrait-missing`. Invalid `kind` is `400` `invalid-query`. Content-Type
+is `image/png`. Opening the card does not generate; use POST when the player asks.
+
+### `POST /api/schools/{id}/people/{personId}/portrait`
+
+Generates (or regenerates) a portrait through SwarmUI on the server. Same `kind` query as GET.
+Success is `201` with `{ "kind", "hasAvatar", "hasFullBody" }` and a `Location` header pointing
+at GET. SwarmUI is not configured when `SwarmUi:BaseUrl` is empty — `503` `swarmui-not-configured`.
+Swarm errors are `502` `swarmui-unavailable`; a slow backend is `504` `swarmui-timeout`. Files
+land under `saves/{id}.portraits/` and survive until the school is deleted.
+
+`GET /api/status` includes `swarmUiConfigured` so the client can disable generate buttons without
+trying POST first.
