Add agentic_mode field to request schema and form data parser to ensure
the agenticMode option is properly passed through the parsing pipeline.
This resolves TypeScript compilation error where agenticMode was required
in LlamaParseOptions but not provided by the processing service.
- Add agenticMode option to ParseOptions interface and Zod schema
- Enable agentic parsing by default for better multi-sheet Excel support
- Fix eligibility extraction to gracefully handle documents without
eligibility criteria by returning empty array instead of throwing error
