feat: add dynamic filename generation for RDAP JSON downloads

Implement context-aware filename generation for downloaded RDAP
responses, replacing the generic "response.json" with descriptive
names based on object type, identifier, and query timestamp.
Filenames follow the pattern: rdap-{type}-{identifier}-{timestamp}.json,
with automatic CIDR conversion for IP networks and proper sanitization
of special characters.
