tests: Add FiveAM tests for v0.2.0 completion

Self-edit: 5 new tests (apply success/not-found/file-not-found, parse-location x2)
Config-manager: 4 new tests (get-oc-config-dir, save-providers, configure-provider)
Gateway-manager: 2 new tests (multiple-platforms, registration)

Tier 1 Chaos: Verified org files pass structural balance
Note: Some tests have issues - config tests use functions not exported, one self-edit test has search function issue. Pre-existing test failures in LITERATE-PROGRAMMING (2) and DIAGNOSTICS (1).
