Grab-bag PR: HTTP QoL, timeout config, SQL transactions

[jsoverson]

This PR is the result of fixes and changes made during production deployments.

It:

• removes global timeouts in favor of per-operation timeouts
• changes 501 errors on missing router to 404s
• changes Internal Server Errors to be more descriptive in logs and less descriptive in the response.
• adds quoted field syntax to access deeply nested fields that have spaces and symbols.
• adds on_error handling to (ms sql server only for now) SQL components with Rollback/Commit/Ignore values.
• adds more differentiation among reported HTTP errors.
• misc other ms sql and http fixes.

Pushed a commit that sync's the vscode rust-analyzer settings with the command used in CI to mitigate PR failures for code that looked OK locally.
