feat: update collectModulePrefixRows to support prior snapshots and enhance CDN/domain prefix collection

Modified the collectModulePrefixRows function to accept an optional priorSnapshot parameter, allowing for more efficient data retrieval by skipping unnecessary CDN fetches. Refactored the logic for collecting prefix rows from AS, CDN, and domain sources to utilize dedicated functions, improving code organization and maintainability. Additionally, introduced caching for module prefix snapshots to optimize performance during refresh operations.
