refactor: replace hardcoded hex colors with design tokens across priority components

- Add DS_COLORS.heat, DS_COLORS.futureCard, INQUIRY_STATUS_META tokens to ds.ts
- Eliminate 4 duplicate RESULT_TYPE_META / TYPE_META constants (now all use ds.ts)
- Eliminate 3 duplicate scoreColor / SCORE_COLOR functions (now all use matchScoreHex)
- HeatBadge: use DS_COLORS.heat.VERY_HOT / HOT tokens
- FutureAvailabilityCard: use DS_COLORS.futureCard.controlled / signal tokens
- IntelligenceMatchCard: import RESULT_TYPE_META from ds.ts, remove primary override
- MatchScoreDisplay: replace local scoreColor() with matchScoreHex()
- CompareColumnHeader: remove local TYPE_META + SCORE_COLOR, use ds.ts + utils.ts
- CompareTableBody: import RESULT_TYPE_META + matchScoreHex, fix #7c3aed → token
- compareUtils: remove TYPE_META + SCORE_COLOR, use dataQualityHex in scoreBar
- Anfragen + AnfragenInquiryItem: deduplicate STATUS_CONFIG → INQUIRY_STATUS_META
- Anfragen: #1e3a5f → 'primary.main', KI alert → futureCard.controlled tokens
- AnfragenMessageBubble: own-message bubble → 'primary.main', AI bubble → tokens
- ScoreBreakdownPanel: #1e3a5f → 'primary.main', #6d28d9 → futureCard.controlled
- ESLint: add warn rule against new hex colors in component sx props
