fix(admin): polish categories

Add accessible names to select-all, per-row select, and per-row
visibility-toggle checkboxes in the table view — none had them,
including the visibility toggle whose <label> wrapped only the input
with no text content (empty accessible name). Tree/grid views already
had aria-label on their row checkboxes; table view was the gap.

New adminCategories.selectAllRows/selectRow/toggleVisibility keys
added across en/ru/hy.
