Both only checked title existence, so editing a stream's rules or a
dashboard's widgets under the same title silently skipped the update
forever. step_dashboard() now diffs the search's queries content
(delete+recreate view+search on change - no subscribers/history to lose,
unlike alerts or streams); step_streams() diffs rules individually by
(field,type,value,inverted) and PUT-updates metadata in place, since
delete+recreating a stream would briefly break live message routing.
Confirmed live on a local test deployment: a false "changed" positive
from search_types list-reordering and from search_servers.json's own
query-format inconsistency (bare string vs the {query_string,type} object
Graylog actually stores) had to be fixed before step_dashboard() settled
into a stable no-op; step_streams() was verified with a full inert
rule-add/remove and a metadata-change round-trip against the live API.
