Add “Copy raw scan” action for nmap engagements

[Copilot]

Recon Deck persisted engagement.raw_input but had no UI affordance to retrieve it. This adds a discoverable copy action for nmap imports while avoiding broken UX for AutoRecon engagements.

• Header action: copy latest raw scan text

  • Added a Copy raw scan control in the engagement header next to existing scan/export actions.
  • Copies the exact persisted engagement.raw_input to clipboard (latest import value).

• Source-aware visibility (no broken AutoRecon button)

  • Introduced getCopyableRawScanText(source, rawInput) to centralize eligibility:
    • allowed: nmap-text, nmap-xml with non-empty raw input
    • hidden: autorecon and empty/missing raw input

• Wiring + targeted unit coverage

  • Passed rawInput into EngagementHeader from engagement page data.
  • Added focused tests for helper behavior across nmap/autorecon and empty input cases.

export function getCopyableRawScanText(source: string, rawInput?: string | null) {
  if (source === "autorecon") return null;
  if (source !== "nmap-text" && source !== "nmap-xml") return null;
  if (!rawInput) return null;
  return rawInput;
}

• Fixes feat: copy the raw nmap output back out of an engagement #79
