fix(admin): Fix Prompt management list not showing version info and add debug diagnostics

Summary:
- Fix Prompt list API response schema missing activeVersion and draftVersion fields
- Fastify was filtering out undefined schema fields, causing version columns to show empty
- Add detailed diagnostic logging for Prompt debug mode troubleshooting
- Verify debug mode works correctly (DRAFT version is used when debug enabled)

Changes:
- backend/src/common/prompt/prompt.routes.ts: Add activeVersion and draftVersion to response schema
- backend/src/common/prompt/prompt.service.ts: Add diagnostic logs for setDebugMode and get methods
- PKB module: Various authentication and document handling fixes from previous session

Tested: Debug mode verified working - v2 DRAFT version correctly loaded when debug enabled
