* fix(sub): address review feedback on subscription info node

- Restore GetSubs contract to avoid unintended remark expansions on non-subscription-body calls.
- Exclude dummy info node from Clash PROXY select group when active server nodes exist.
- Track hasEnabledClient and set traffic.Enable in JSON and Clash paths so status tokens evaluate correctly.
- Deterministically sort client emails across subscriptions before selecting primaryEmail.
- Consolidate duplicated info-node evaluation logic into resolveInfoNodeRemark helper.
- Remove redundant pure-getter test from setting_sub_info_node_test.go.
