Rewrite tooltip with concise, actionable content focused on real-world usage

Transform verbose tooltip into practical guidance:

New structure:
• "What this does" - Clear one-liner about functionality
• "When to use" - 4 concrete use cases (album pages, batches, collages, documents)
• "Quick fixes" - Problem → solution pairs with specific values
• "Setup tips" - Practical scanning advice (DPI, gaps, backgrounds)
• "Heads-up" - Important limitations and workarounds

Benefits:
- Shorter, scannable content
- Action-oriented language ("increase Tolerance to 30-50")
- Real-world scenarios users actually face
- Specific numeric guidance instead of vague descriptions
- Proactive troubleshooting before problems occur

Content matches professional but accessible tone throughout.
