Keep deleted cards in grid until next scan

Mirror the redact behaviour for the card delete button (🗑): instead of
removing the card on success, mark the item _deleted and keep it in the grid
— greyed via card-resolved, shown with a red "🗑 Deleted" badge, action
buttons hidden so it can't be re-processed. The grid is rebuilt on the next
scan run, clearing the markers. results.js only — no server change.

 ### Changed
 
-- **Redacted cards stay in the grid until the next scan** — previously redacting a card (✏) removed it from the grid and from `S.flaggedData`/`S.filteredData` immediately. Now the item is kept and marked redacted: the card is greyed (`card-resolved` styling), shows a `✏ Redacted` badge, and its delete/redact action buttons are hidden so it can't be re-processed. The operator can see what was handled during the session; the grid is rebuilt on the next scan run, which clears the redacted markers. Implemented with a `_redacted` flag in `results.js` (`appendCard` + `redactItem`); no server change.
