Schema bump that lets the universal <FilterBar> tell shape-list which
row interaction to wire (navigate / complete_toggle / approve / none).
Defaults to navigate when empty so existing SystemView definitions and
saved user views continue to render rows that route to the per-kind
detail page.
Validator extended; pure-Go test cases over every enum value + reject.
TS mirror updated in client/views/types.ts. No DB migration — the
field is purely additive on the JSON shape.
