Manually Triggered Automation with Error Handling

## Step 1. Store Workflows Credential Mappings to Database

We'll achieve this by querying n8n's built-in API to query all workflows, extract the credentials list from the nodes within and then store them in a SQLite database. Don't worry, the actual credential data won't be exposed! For the database, we'll abuse the fact that the code node is able to create Sqlite databases - however, this is created in memory and will be wiped if the n8n instance is restarted.
