fix: GetModuleContext: use config from context instead of from envar (#…

…1534)

Fixes #1352

With this change, the behavior is:
- `ftl dev examples/go`
  - uses `ftl-project.toml` in the gitroot if it exists
- `FTL_CONFIG=ftl-project-inline-a.toml ftl dev examples/go`
  - uses `ftl-project-inline-a.toml`
- `ftl dev examples/go --config=ftl-project-inline-b.toml`
  - uses `ftl-project-inline-b.toml`
- `FTL_CONFIG=ftl-project-inline-a.toml ftl dev examples/go --recreate
--config=ftl-project-inline-b.toml`
  - uses `ftl-project-inline-b.toml`
