fix(l2): _route_experts accepts both enum and string for domain

The test fixture passes dummy_spec.domain = 'research' (string),
while ArsenalRun passes spec.domain = Domain.RESEARCH (enum).
The function compared domain to string literals in a list, so it
would silently never match an enum.

Use hasattr(value) to handle both shapes; this also makes the
function not blow up on strings.
