Apply quick wins and pipeline fixes for integration tests:
- Remove is_test_data flag from location inserts
- Increase test delay from 2.5s to 5s and add delays between suites to curb rate limiting
- Replace [object Object] error formatting with formatTestError across 10 test suites (31 edits) and add import
- Refactor unit/conversion tests and performance tests to use the approval pipeline
- Extend edge function handling by ensuring item_ids are included in idempotency key inserts (edge function fix)
- Update auth, data integrity, edgeFunction, moderation, performance, submission, unitConversion, and versioning test files accordingly
