feat(web): full-width sortable/filterable objects table with URL state (#44)

Replace the narrow ObjectList with a full-width ObjectsTable whose state
(sort/order/q/visibility/limit/offset) lives entirely in the URL via
useSearchParams. Sortable headers toggle sort+dir with aria-sort, a
debounced quick-filter and visibility chips mirror the search-panel
pattern, and a pagination footer offers prev/next + page-size select.
Rows deep-link to /objects/:id preserving the query string.

useObjectsPage now takes an ObjectListParams object (sort/order/
visibility/q) with keepPreviousData. ObjectsPage renders the table as
the full-width landing view, surfacing the nested <Outlet/> detail as a
simple right-side panel only when a :id child route is active (Phase 3
makes this responsive). object-list.tsx and its test are removed.
