Closes#38, #39 and #40; adds the client side of #41.
- Every request goes to /api/v1. MusicServerClient gets a token with
Settings.api_password the first time one is needed, reuses it, and on a
401 gets a new one and sends the request once more. Switching server gets
a new token too. Callers never see the token.
- Sync is started with POST, as MusicServer 5.0 requires.
- The client has every endpoint in the server's OpenAPI spec, including
statistics, soundtracks and songs by UUID, version, downloads and tokens.
- tools/generate_api_types.gd generates a typed class per schema in
server/openapi.json into server/generated/. Song info, statistics and
versions are passed to callers as these classes. A list the server sends
as null is an empty list.
- FakeHttpTransport hands out tokens and answers 401 without one, so every
test goes through the token flow. New tests cover the token handling,
every endpoint and each generated class.
main/ holds the main window and top bar, quiz/ the quiz and its parts,
player/ the music player, popups/ every popup and what they share, data/ the
songs, players, playlist and settings, server/ the MusicServer client,
common/ the list row and GameLog, and themes/ the themes and style boxes.
The quiz (song, playlist, players, music player and the popups opened from
it) moves into Quiz.tscn and the top panel into TopBar.tscn. The main window
keeps only the top bar, the quiz and the popups opened from the top bar, so
other views can be added next to the quiz later. Every node keeps its place
on screen.
Screenshots of every UI state before and after are pixel-identical, and a
layout test checks each node against a baseline taken before the split.
