fix: Update sample model return values to match guidance.

[devinglauner]

Issue #, if available: n/a

Notes

Updated sample model output data and test files to align with the current guidance for model return values. This change standardizes the output format across sample data files and ensures test consistency.

Changes

• Updated source code for aircraft, centerpoint, and flood models to use standardized output format:
  • Changed from bounds_imcoords to imageBBox property naming
  • Replaced feature_types object with featureClasses array containing IRI and score
  • Updated geometry structure to use null instead of Point coordinates
  • Added modelMetadata with model name, ontology name, and version
  • Updated property structure for mask handling (geom_imcoords → imageGeometry)
• Updated test files to match the model return changes
• Updated copyright year from 2024 to 2025
• Regenerated sample output data to reflect the new standardized format

Impact

• Ensures test models return values consistent with current model output guidance
• Standardizes property naming conventions across sample data
