fix(workflows): route 'workflow status --json' errors to stderr (#3520)

* fix(workflows): route 'workflow status --json' errors to stderr

The workflow_status run_id error paths (FileNotFoundError -> 'Run not found',
ValueError -> invalid run) used the stdout console and fired before the
json_output branch, so 'specify workflow status <bad-id> --json' wrote a
Rich-rendered error to stdout and corrupted the JSON stream a consumer would
json.loads(). Route both through _error_console(json_output) so they go to
stderr under --json, matching the sibling 'workflow run'/'workflow resume'
commands (which use the identical RunState.load try/except) and the documented
stdout-purity contract.

Test asserts the not-found error appears on stderr and stdout stays empty under
--json (fails before: the error was on stdout).

* test(workflows): cover the ValueError handler in workflow status --json purity

The stderr-routing fix reroutes both the FileNotFoundError and ValueError run_id
handlers, but the test only exercised FileNotFoundError — a regression of the
ValueError path back to stdout would have gone uncaught. Add a ValueError case
(RunState.load raising) asserting the same stderr-only / empty-stdout behavior.
