fix(admin): polish products

Add accessible names to the table-view select-all and per-row
checkboxes — they had none, while the grid-view equivalent already
did (product name via aria-label). New adminProducts.selectAllRows/
selectRow keys added across en/ru/hy.

Reviewed toolbar, filters, bulk actions, empty/loading states, and
grid view: all buttons already route through app-button (own
:focus-visible), empty state already uses shared EmptyStateComponent.
No orphaned bindings or corrupted glyphs found.
