Run the SDK live tests against the test seeder

tools/sdk-live-tests/run.sh builds the server with unsafe_test_mode and runs
the live tests of the SDK's e2e/wasm suite. For SDK versions whose tests log in
to one given account, each user test vector with a master password is seeded
with its vault on a fresh server; for versions that seed their own accounts,
the tests get the seeder's address. Every vector runs, then a summary.

The workflow runs it by hand, and on changes to the seeder or the runner.

+//! A seeder API for the end-to-end tests, only in builds with the `unsafe_test_mode` feature: it creates accounts with

+//!
+//! It answers the calls the SDK's live tests make to upstream's `util/SeederApi` (`POST /seed` with a scene,
+//! `DELETE /seed/{playId}`), under `/test/seeder`. Each request needs HTTP basic auth with `TEST_SEEDER_USERNAME` and
+//! `TEST_SEEDER_PASSWORD` from the environment; without both, every route answers 404. Seeding needs an `X-Play-Id`
+//! header, and destroying a play deletes the accounts seeded under it. Plays are kept in memory, which is enough for a
+//! test server that starts on an empty database.
+//!
+//! Scenes:
+//! - `SingleUserScene`: a V1 account for an email and password, under a mangled address like upstream's, with
+//!   PBKDF2 at upstream's default of 5000 iterations.
+//! - `TestVectorUserScene`: one of the SDK's user test vectors (`test-vectors/users/*.json`), stored as it is: the
+//!   account and its vault are already encrypted. Unlike upstream, the address isn't mangled, since our master
+//!   password salt is the email, so a vector can be seeded once at a time. Text Sends are stored too.
