feat: F008 AI need builder — full spec compliance (editable criteria, grouped sections, needService.create)

- NeedInput: Reset button, Asset-Type Quick Select chips, 3 typed examples
- ExtractedFieldRow: inline edit mode (pencil → TextField, Enter/blur commits)
- CriteriaReviewPanel: 3 grouped sections (Hard Facts, Soft Factors, Must-haves) + AI Assumptions + Missing Information; all 14 criteria fields shown and editable; onCriteriaChange propagates typed edits to parent
- FollowUpPanel: Rückfragen neu generieren button triggers onReparse
- NeedCardPreview: Need Title input, Confidence Summary with progress bar, Missing Critical Fields alert, low-confidence draft label
- AISearch page: editedCriteria state (mutable copy of parse result), handleReparse via generateFollowUpQuestions, handleSave calls needService.create() with full CreateNeedInput mapping, low-confidence → status DRAFT
