feat: detect and flag inconsistent hash sizes across adverts
Tracks all hash_size values seen per node. If a node has sent adverts
with different hash sizes, flags it as hash_size_inconsistent with a
yellow ⚠️ badge on both side pane and detail page. Tooltip mentions
likely firmware bug (pre-1.14.1). Stats row shows all sizes seen.
