[thomhurst]

Summary

• add shared JSON Add record modal for DynamoDB and Cosmos DB NoSQL
• add generic NoSQL item creation route and DynamoDB PutItem adapter support
• validate DynamoDB S, N, and B keys while preserving large numeric keys
• keep Cosmos document editor focused on updates and prefill required create fields

Testing

• pnpm lint
• pnpm type-check
• pnpm build
• focused API tests: 57 passed
• pnpm test: 728 passed; 1 pre-existing Windows-only ZIP test failure from CRLF parsing of unzip -Z1 output

Closes #207

Greptile Summary

The PR adds shared JSON-based record creation for DynamoDB and Cosmos DB, with a generic NoSQL creation API and DynamoDB key-aware marshalling.

• Adds the NoSQL item creation route, client method, and adapter contract.
• Implements DynamoDB PutItem support with validation for string, numeric, and binary keys.
• Adds a reusable record modal and integrates it into the DynamoDB and Cosmos DB explorers.
• Rejects unquoted unsafe integer keys before DynamoDB marshalling while preserving quoted large numeric keys.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the previously reported unsafe numeric key rounding is prevented before marshalling, while quoted large numeric keys retain their exact value.
