Add saves and board support for manual testing

The board gains an "A tester" column for the checks that need a person:
the project-board hook now reads it, so a commit that mentions one of its
cards moves the card instead of adding it to a second column. A test that
runs only with MAKE_TEST_SAVES=1 writes the backup those checks import,
built from the local ROM and kept out of git.

+Asked for the checks only a person can do. The board gained an "A tester"
+column (between En cours and Fait) with #46 (Fly map, flight and landing),
+#47 (Teleport and the Escape Rope outdoors), #48 (touch screens, part of
+#40), #49 (screen reader, related to #38) and #50 (Dig and the Escape Rope
+in Dark Cave, blocked by #31). `scripts/project-board.mjs` now also reads
+that column, so a commit mentioning one of those cards moves it instead of
+adding it to a second column.
+
+`tests/human-test-saves.test.ts` writes the backups the cards use, only with
+`MAKE_TEST_SAVES=1` and the local ROM: `test-saves/fly-teleport.crystal-save.json`
+(ignored by git, as it holds names read from the ROM). It reloads each save
+in a fresh world before writing it; importing it through Savegames and using
+Teleport then Fly was checked once in Chromium and WebKit.
+
+Not made into cards, because they can be automated: emulator comparisons
+of the flight paths and of the Teleport/Dig warps through the reference
+harness.
