fix: invert shoring ratio logic — higher offshore = better

The shoring indicator logic was backwards. In the business context,
higher offshore = more cost-efficient = GOOD.

Inverted logic:
- Green: offshore >= threshold (target met, e.g. >= 55%)
- Yellow: offshore close to threshold (threshold-10 to threshold)
- Red: offshore below threshold (too little offshore, too expensive)

Updated:
- ShoringIndicator: getSeverity() inverted, badge text updated
- ProjectModal: "Max Offshore" renamed to "Min Offshore" with new tooltip
- AI Tool: status text reflects "target met" vs "below target"
- Tool description: "higher offshore is better, threshold is minimum"
