Adds the four POST routes whose state-layer support was already dispatched by the manual_edit projector (edge_trust, edge_summary, memory_pov_summary) plus a new edge_knowledge_fact dispatch branch for add/remove fact list manipulation. Drawer template gains editable textareas, sliders, and add/remove fact controls. Remove semantics on knowledge_fact match by string (not index) so concurrent edge_update events appending facts between drawer renders don't desync the form.
