Assets page: show model name instead of UUID, row index instead of raw ID, add filters

Model ID column now shows "Manufacturer Name" (looked up from the
already-fetched asset-models list) instead of the raw model_id UUID.
The ID column shows a 1-based row index within the current filtered view
instead of the AssetItem UUID -- the id itself was never actionable in
the UI (no per-row link/detail view exists), just clutter at this scale
(~600+ rows after the real-data import).

Added a filter bar: free-text search (matches serial_number or asset_tag,
case-insensitive substring), status dropdown, model dropdown -- all
client-side (assetItems is already the full list via useApiList, and
filtering ~600 rows in memory is trivial, no need for a server-side
filtered endpoint at this scale).

tsc/lint clean, no Vitest coverage -- same deviation as the rest of this
branch, see CLAUDE.md.
