Fixed multiple issues with the docs page card-based document view:
**Card Overflow Fixed:**
- Added overflow-x-hidden to #document-content container
- Added w-full max-w-full to card-grid-container
- Added w-full to grid itself
- Added max-w-full overflow-hidden to individual cards
- Cards now stay within container boundaries at all viewport sizes
**Long Title Wrapping:**
- Added insertSoftHyphens() method to break CamelCase words
- Inserts soft hyphens (­) before capitals in compound words
- Examples: "InstructionPersistenceClassifier" → "InstructionPersistenceClassifier"
- Titles now wrap intelligently without being cut off
**Colour Legend (Option C):**
- Added toggle button (ℹ️) next to ToC and PDF buttons
- Popup shows all 5 colour codes with descriptions
- Translated to EN ("Colour Guide"), DE ("Farbcode"), FR ("Guide des couleurs")
- Fixed colour square visibility (bg-500 with borders instead of bg-400)
- Click outside to close functionality
**Card Sequencing:**
- Cards now display in original markdown document order
- Removed groupByCategory() grouping logic
- Removed category header sections
- Color coding preserved based on section category
**Category Fallback Bug:**
- Fixed invalid fallback category 'downloads-resources' → 'resources'
- Ensures uncategorized documents go to valid category
**Database Migration:**
- Added scripts/move-guides-to-resources.js
- Moved 3 implementation guides from getting-started to resources
- Getting Started now contains only: Introduction, Core Concepts
- Resources now contains: Implementation guides
**Result:**
✅ Cards respect container width (no overflow)
✅ Long titles wrap with hyphens (no cutoff)
✅ Colour legend accessible and translated
✅ Cards in logical reading order from markdown
✅ Implementation guides in correct category
