v3.22.7: a raised card error honours the step's on_fail

The runner's step loop caught an exception and hard-coded status "error" +
stop, ignoring on_fail - so a file-read of an absent optional file
(re-verified live on 3.22.6: MF/A153/49AC, note "6a82: Wrong parameters -
File not found", on_fail "warning" still stopped the run) could not express
the "read an optional file" pattern (49AC is documented optional: its
absence means no menu password).

The handler now treats a raised error as a failed "Error" check at the
step's level (the message as actual/detail and the note): on_fail "warning"
warns and the run continues, the default still stops; the drain-if-pending
behaviour is unchanged.  Every raised exception is treated the same - the
two "file absent" raise paths (pySim's SwMatchError for model files and
probe_file's RuntimeError with the decoded SW for custom FIDs) cannot be
told apart by type, and load-time validation (normalise_script) stays
strict.

Docs: the guide's on_fail paragraph and run-errors list (the 6A82 bullet),
api.md and help EN/RU.  Tests: a raising file-read with on_fail "warning"
warns and the next step runs; without on_fail the run still stops.
