feat(recipes): show a summary modal after rematch runs

Replace the post-run toast cascade and the standalone L4 results modal
with a summary modal modeled on the batch download summary: 3-state
header, stat cards (matched / needs review / unresolved / errors),
an L4 review table with per-entry undo, and a copyable report. Wired
into the global, bulk and single-recipe rematch entries; complete
no-op runs keep the lightweight toast. Obsolete results-modal code,
styles and i18n keys are removed.
