fix: GOMEMLIMIT for all devices, cascade delete orphans, logread cleanup

Browse Source 
- GOMEMLIMIT: remove 256MB RAM threshold cap. Now applies to ALL
  devices. Formula: min(35% RAM, 512MB). mem_scale respected.
  Fixes sing-box eating 500MB+ on 2GB routers with no limit.

- Cascade delete: when a routing section is deleted, child UCI entries
  (subscription_url, urltest, priority_group, priority_level,
  section_interface) are now removed. Prevents orphaned entries that
  corrupt config generation.

- Migration cleanup: orphan_section_interfaces now cleans ALL child
  types, not just section_interface.

- Watchdog logread: kill orphans in stop_runtime(), add SIGTERM/SIGINT
  handlers in uloop mode (previously only in fallback mode).
