fix(table): smooth list empty/loading transitions, no layout jump on entry

Reserve a stable block for the empty/loading state (matching the NoResult
height) and fade the empty state in, so entering a list page no longer jumps
between spinner, empty result, and rows. Apply scroll-table to the antd main
lists and pass emptyMinHeight to the SealTable-based lists.
