Fix veilid-wasm errors so it compiles, emit TypeScript types.

- `wrap_api_future` function did not exist, so I used `wrap_api_future_plain` since the return type appears to be a base64 encoded string.
- Argument order for `create_dht_record` was incorrectly swapped.
- `veilid_core::json_as_base64` does not exist, don't exactly know what to replace it with for serde serialization, but I commented it out for now.
- Removed `--no-typescript` flag from `wasm-buildgen` so that TypeScript types are emitted.
