Fix: accept task_code/milestone_code as identifiers, add /config/status endpoint

- All /tasks/{task_id} endpoints now accept both numeric id and task_code string
- All /milestones/{milestone_id} endpoints (misc.py) now accept both numeric id and milestone_code
- Added _resolve_task() and _resolve_milestone() helpers
- GET /config/status reads initialization state from config volume (no wizard dependency)
- MilestoneResponse schema now includes milestone_code field
- Comments and worklog endpoints also accept task_code
