Prevent Routing.Type=auto from enabling dhtserver mode if have too low of limits

## Done Criteria
A Kubo node with ``Routing.Type=auto`` doesn't attempt to be a DHT server if the following additional conditions aren't met:
1. Swarm.ResourceMgr.System.ConnsInbound > 800 AND
2. Swarm.ResourceMgr.System.StreamsInbound > 800 AND
3. Swarm.ResourceMgr.Protocol.kaddht.StreamsInbound > 800 AND
4. Swarm.ConnMgr is enabled

(Existing logic of ensuring the node is publicly dialable will still apply.)

## Why Important
If a "dhtserver" node advertises itself to the DHT but has too-low of hard Swarm.ResourceMgr limits, then it won't be able to function and be of value to the DHT and instead degrades performance.

## Notes
* Kubo maintainers have observed instances of this happening in practice.
* See notes in https://github.com/ipfs/kubo/issues/9545 about:
* Why 800
* Why ``Swarm.ResourceMgr.System.StreamsInbound`` in addition to ``Swarm.ResourceMgr.System.Streamsnbound``
