Log DB query & environment values

[kmcginnes]

Description

Sends DB query to server to log. Also sends broad context at the explorer request level to the server.

Logging

• Add DB query string logging to proxy server at debug level
• Logs client side explorer requests to server at info level
• Adds explorer request logs to all client side explorers (openCypher and SPARQL)
• Fix bug in remote logger creation, where the remote logger would never be created
• Send logs to both client and server when using remote logger
• Rename logger to remoteLogger to be more clear when it is being used
• Don't log in the request middleware for path /logger to reduce noise

Environment Values

Reworked how environment values are parsed.

• Move access to process.env to a single place in env.ts
• Add Zod schema for environment values the server cares about
  • Default values are used if the key is missing or undefined
• Parse process.env and print out any errors
  • Any errors will terminate the server

Validation
