Owner

Part of EPIC-21 (#24). See LLD: docs/lld/enrollment-session.md

What

Implement the ProviderEnrollment trait (defined in S1/#31) for all three session-based providers:

Face (linux-hello-face/src/provider.rs)

Wrap existing enroll() loop with EnrollSignal emission (PoseRequired, PoseCaptured, PoseRetry, Frame)
Return rmp_serde::to_vec(&embeddings) as credential bytes

FIDO2 (linux-hello-fido2/src/provider.rs)

Emit EnrollSignal::Step { instruction: "tap_key" }
Call make_credential, return rmp_serde::to_vec(&credential)

Fingerprint (linux-hello-fingerprint/src/provider.rs)

Emit EnrollSignal::Step { instruction: "place_finger" }
Delegate to existing FingerprintProvider::enroll (fprintd-backed)
Return empty Vec<u8> (no local DB write needed)

Dependencies

S1 / #31 must be merged first
