fix: use predefined values for tool calls, improve completion flow

- System prompt now specifies exact predefined values for services/industries/timelines
- Agent instructed to call complete_brief IMMEDIATELY when name+email confirmed
- Chip labels fall back to raw value for unknown keys instead of showing i18n path
- Added completion transition logging
