Cardano Updates

Signed-off-by: Aurora Gaffney <[email protected]>

The tests were disabled in #7567 due to intermittent failures where
the service would report "Program file is empty" for valid programs.

Root cause: Race condition between test file writing and service reading.
The test's writeFile creates an empty file then writes content, but the
service (polling at 100ms) could read the file before content was written.

Fix: Use atomic file creation in submitProgram and submitProgramFlat by
writing to a temp file first, then using renameFile for atomic move.
This mirrors the pattern already used by the service for output files.

- Remove skip_reason from chronological_order_descending.json
- Update expected response to match v2.1 operation ordering (da62f24)
- Add total_count to search volatile fields to prevent false failures
