feat(diarization-ui): add project-batch execution and user_prompt to run page

- New tab layout on /run: single-document vs. project-batch mode
- POST /run/project enqueues one analysis job per transcript in a project
- Optional user_prompt field on both modes for extra context to the LLM
- DB migration: adds user_prompt column to jobs table
- LLM prompt builder includes ZUSATZINFOS block when user_prompt is set
