tests: add missing required event fields in tests that build dicts directly

Some test fixtures construct event/PDU dicts inline rather than via
make_test_event — typically because they then run them through
add_hashes_and_signatures or otherwise depend on the exact dict shape.
Add the format-required fields (depth, hashes, auth_events,
prev_events, ...) inline in those cases so they keep working under
the strict (Rust-bound) constructor.
