[fix](trx-rs): resolve all clippy warnings

- remote_client tests: add missing server_connected field and import
  AtomicBool in the test module
- pskreporter: replace map_or(true, …) with is_none_or and
  repeat(x).take(n) with repeat_n(x, n)
- dsp.rs, scheduler.rs: suppress intentional too_many_arguments with
  #[allow(clippy::too_many_arguments)]
