[LIMS-1700] Make classification values optional

[gfrn]

JIRA ticket: LIMS-1700

Summary:

Since sometimes the pipeline fails to insert fourier completeness or estimated resolution values, we must consider these optional instead of throwing errors.

Changes:

• Make fourier completeness, estimated resolution, rotation and translation accuracy optional in classification data endpoint
• Check if movie is valid before returning movie information

To test:

• Assuming you're pointing at the restored database, send a GET request to https://local-oidc-test.diamond.ac.uk:9000/api/autoProc/110625162/classification?limit=8&page=0&sortBy=particles&classType=2d&excludeUnselected=false, ensure 200 is returned
• Send a GET request to https://local-oidc-test.diamond.ac.uk:9000/api/movies/82012317, ensure 404 is returned
