fix(xray): keep source- and domains-scoped routing rules when an inbound is deleted

removeInboundTagFromRules drops a routing rule whose inboundTag list becomes
empty only if the rule has no other matcher, but routingMatcherKeys omitted
xray-core's canonical source and domains keys. A rule scoped by source or domains
(common in hand-authored or imported configs) therefore lost its whole body —
including a security-relevant block — when its single listed inbound was deleted,
instead of just having the tag trimmed. Recognize source and domains as live
matchers.
