feat: implement preferred port allocation and per-address enable/disable

- Add AvailablePorts::try_alloc() with SSL tracking (BTreeMap<u16, bool>)
- Add DerivedAddressInfo on BindInfo with private_disabled/public_enabled/possible sets
- Add Bindings wrapper with Map impl for patchdb indexed access
- Flatten HostAddress from single-variant enum to struct
- Replace set-gateway-enabled RPC with set-address-enabled
- Remove hostname_info from Host; computed addresses now in BindInfo.addresses.possible
- Compute possible addresses inline in NetServiceData::update()
- Update DB migration, SDK types, frontend, and container-runtime
