korrespond v1 premiere: Bedrock routing, engine picker, journal auto-save + status

- KorrespondAgent: add resolveDeployment() helper; fix classify/translate to use
  Haiku via Bedrock, draft to use Haiku (quick) or Sonnet (thorough) — fixes broken
  withDeployment('gpt-4o-mini') calls when DBN_BEDROCK_ENABLED=true
- korrespond.php: add Quick/Thorough engine picker (case_toggle already present)
- korrespond.js: pass engine in request payload
- api/korrespond.php: accept user-selected engine, auto-save to case_tool_results
  for paid users after each successful run, update deployment log label
- CaseResults: add korr_status to listForUser SELECT, add updateStatus() method
- result-action.php: add set_status action for correspondence journal
- account.php: show status dropdown (Draft/Sent/Reply received/Resolved) for
  korrespond entries in #analyses, wire JS change handler to result-action.php
