Add centralized route registry (`secubox-route`) in secubox-core to eliminate
route management duplication across metablogizerctl, streamlitctl, and
mitmproxyctl.
New features:
- `/etc/config/secubox-routes` - UCI config for central route registry
- `/usr/sbin/secubox-route` - CLI for route management (add, remove, sync)
- Import routes from HAProxy, MetaBlogizer, Streamlit with source tracking
- Auto-sync to all mitmproxy instances on route changes
- Skip wildcard domains and LuCI (port 8081) routes
Updated services to use centralized registry:
- metablogizerctl: Use secubox-route add instead of mitmproxyctl sync
- streamlitctl: Use secubox-route add with domain/port params
- peertubectl: Use secubox-route add for emancipation
- vhost-manager/mitmproxy.sh: Prefer secubox-route when available
- mitmproxyctl: Delegate to secubox-route import-all for sync-routes
This prevents route mixups between services and provides a single
source of truth for all WAF routing configuration.
