[FEATURE] Improved Test Suite for Python ROR Reconciler

[adambuttrick]

Summary

Build a comprehensive test suite for the Python reconciler that covers all endpoints and specifically handles ROR API v2 merge/redirect behavior. The current Ruby implementation has limited test coverage. The Python port should include tests that validate reconciliation logic against realistic ROR API responses.

Tests

GET /heartbeat

• Returns 200 with JSON containing status, version, PID, Python version
• Validates response schema

GET /reconcile (service metadata)

• Returns correct W3C Reconciliation API service manifest
• Includes service name, identifierSpace, schemaSpace, default types, preview and suggest metadata

POST /reconcile (reconciliation queries)

• Single query returns up to 5 scored results with ROR IDs, names, and types
• Batch queries (multiple q0, q1, ... keys) return independent result sets
• Empty/whitespace query returns empty results
• Special characters in query names (; & / ?) are handled correctly
• Query matching an exact organization name returns that org with a high score and match: true
• Query with no matches returns an empty result list

GET /suggest

• Returns suggestions matching a prefix
• Empty prefix returns empty results
• Results include id, name, and description fields

GET /flyout

• Returns HTML snippet and ROR ID for a valid organization
• Invalid ROR ID returns appropriate error/empty response

GET /preview/*

• Returns rendered HTML preview for a valid ROR ID
• Handles both bare ROR IDs and full https://ror.org/... URLs
• Invalid ROR ID returns appropriate error

GET /

• Redirects to https://www.ror.org

Integration tests

• End-to-end test with a running app instance that runs through the full request lifecycle from HTTP request through ROR API call (mocked) to response rendering
• Verify CORS headers are present on responses

Acceptance criteria

• Test suite covers all 7 endpoint routes
• Tests run in CI (GitHub Actions) and block deployment on failure
• Tests execute without network access (all external HTTP calls mocked)
