Reapply: feat(api): Allow configuring the API URL at runtime

[lordrip]

Reapply #1687

Context

Currently, the API URL is retrieved using an environment variable available at build time only. This creates friction in the VSCode extension context as it blocks running more than one instance of it.

Changes

This commit adds a constructor parameter to optionally receive the API URL so it can be overridden through the VSCode bootstrap process.

The API URL still defaults to the same environment variable provided at build time.

Example running at port :9000

fixes: 1451
