docs: remove deprecated config command references

- Remove all references to `promptcode config` command
- Update documentation to reflect API keys are only set via environment variables
- Simplify configuration instructions across all docs
- Update error messages to only mention environment variables
- Remove `--set-<provider>-key` flags from examples

This change improves security by ensuring API keys are only handled through
environment variables, never stored in config files.
