feat: surface inventory timestamps on nodes
Add creation_date, last_scan and last_modify to the node inventory and the
right-hand detail panel (last_seen already shown):
- creation_date -> existing created_at column
- last_modify -> existing updated_at column (bumped on any node change)
- last_scan -> new column, stamped when a scan observes a node by IP/MAC
- last_seen -> unchanged
Backend: new nodes.last_scan column + idempotent migration, NodeResponse
field, scanner stamps matching canvas nodes per scanned host. Frontend:
NodeData fields + DetailPanel rows with UTC-safe timestamp formatting.
