Export Parquet Files with an Empty Dataset

[najuna-brian]

Description

Verifies that the synk data export command handles the edge case of a server with zero observations gracefully, without crashing or producing a corrupt file.

Steps

1. Ensure you are logged in: run synk login with valid admin credentials
2. Confirm the server has zero observations (fresh server or wiped database)
3. Run synk data export exports.zip
4. Observe the output and exit behaviour

Expected Result

The command either returns a clear message stating there is no data to export, or produces an empty ZIP file. The command must NOT crash, panic, or produce an unreadable file. Exit code should be 0 for empty export or a non-zero code with a clear explanation.

Actual Result

(To be filled during testing)
