fix: panic when ftl-controller trying to access config and secrets (#…

…1592)

Fixes #1588 by providing a workaround to load `ftl-project.toml`s from
paths specified in command line args or `FTL_CONFIG` env.

I doubt we want this long-term given the work that is being done with
AWS secrets manager, db config, and `AdminService` but this might help
unblock the deployment work for now.
