Replace tree_node.html include with inline Django 6.0 partialdef

The recursive tree_node.html file is folded into tree.html using
{% partialdef tree_node %} / {% partial tree_node %}. Context is passed
via {% with node=child %}, which works because PartialNode uses
DeferredSubDict for runtime lookup, making recursive self-reference safe.
