- Refactor TimeParsingService to parse time strings to UTC only
- Remove minutesAgo from RadarFrame and FrameMetadata models
- Update CaptureFramesStep to extract UTC timestamps directly
- Update CacheService to store/load ObservationTime instead of MinutesAgo

- Filter frames that are too close together (< 4 minutes apart)
- Preserve original folder structure while pruning filtered frames
- Sort folders by earliest frame time to maintain chronological order
- Add validation to detect folder overlaps that could cause out-of-order frames
- Capture all 7 radar frames (0-6) instead of single screenshot
