Introduces a small, isolated interface for reading a JWT from a file path — the first piece of the upcoming Conjur JWT authentication path, split out on its own since nothing else in this PR depends on it yet.
identity.go mixed the shared client/token-cache plumbing with the CyberArk Identity username/password (UP) login flow. Move the UP-specific code into username_password.go so the shared plumbing stays easy to find once a second login mechanism (Conjur JWT) is added alongside it. No behavior change — pure extraction, plus unexporting ActionAnswer and exporting the mock's success credentials for other packages' tests.
The Service Discovery API returns several independently-hosted services; the authn-jwt exchange this PR series adds is served by secrets_manager, a different host from identity_administration. Add a SecretsManager field to Services and parse it, so callers have it available — nothing reads it yet, that lands in a later PR alongside the client that needs it.
Exchanges a projected ServiceAccount JWT (via jwtsource) for a Conjur access token through the authn-jwt endpoint, and authenticates requests with it as identity.RequestAuthenticator. Nothing wires this in yet — that's the next PR, once both this and the legacy identity client exist side by side. The identity returned for audit tagging is the token's own sub claim when it can be extracted, falling back to the configured service ID otherwise, so an unusual token shape degrades rather than fails the request.

Summary
Part 4 of the SMS/Conjur JWT authentication series (split out of #817). Stacked on #818, #819, and the service-discovery PR — diff will shrink once those merge.
