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.
