test: make both suites pass on Windows

Most of these failed on Windows for reasons that had nothing to do with the
code under test, which is how real Windows defects hid among them:

- Read and write files as UTF-8, and talk to Node in UTF-8. read_text(),
  write_text() and subprocess text=True use the locale codepage, cp1252 on
  Windows: "é", "—" and "→" arrived as "?" or crashed, some sixty tests.
  Calls to PowerShell and schtasks are left alone -- they answer in the
  console codepage.
- Import ESM harness modules by file URL (as_uri): a raw "C:\..." path is not
  a module specifier.
- test_cli_golden: mask the tmp path in its JSON-escaped form, spell it the
  POSIX way, record on Linux, mask the protocol version (the recording had
  failed everywhere since the MNP 4.0 bump) and argparse's version-dependent
  quoting; point USERPROFILE at the tmp home, or `member invite` and
  `operator pair` wrote their codes into the developer's profile.
- test_disk_io_off_loop: expect what a free loop can reach on the platform's
  timer, 15.6 ms on Windows, not an assumed 5 ms.
- test_root_paths_are_operator_only: expect the OS's spelling of the path.
- test_audio_meta_cache: find ffprobe with shutil.which.

Node suite on Windows: 1489 passed, none failed. Hub suite: 3 failures left,
all older than this change (two SQLite concurrency tests, one transfer resume).
