Decompose the monolithic internal/provider/telemost package into two
orthogonal layers: engine/goolom (Yandex proprietary SFU wire protocol —
WebSocket signaling, dual pub/sub PeerConnections, DataChannel, telemetry)
and auth/telemost (HTTP connection-info fetch → engine.Credentials).
Add engine.Config.Refresh callback so Goolom can obtain fresh peerID and
credentials on every reconnect without a direct dependency on the auth
package. engine_adapter wires the Refresh closure from authProvider.Issue.
Delete internal/provider/ entirely (telemost was the last tenant) and
remove the now-obsolete provider_adapter + its test from builtin.

Split the SaluteJazz provider along the same engine/auth seam used for
WB Stream:
- internal/engine/salutejazz — Sber WS+SDP signaling engine (pub/sub
split, _reliable data channel, length-prefixed DataPacket envelope).
Consumes URL/Token/Extra[password] from engine.Config; no embedded
HTTP/auth logic. Registered as engine "salutejazz".
- internal/auth/salutejazz — create-meeting + preconnect flow.
Implements auth.Provider (Engine() → "salutejazz") and
auth.RoomCreator. Accepts cfg.RoomURL in "<roomID>:<password>" form
for join, or empty / "any" / "dummy" for create-on-the-fly, matching
the legacy provider.
The carrier name "jazz" now goes through registerEngineAuth.
engine.Config gains an Extra map so auth providers can pass engine-
specific fields (password here); engine_adapter forwards
auth.Credentials.Extra into it.
session.Gen for jazz uses the auth.RoomCreator capability. Output now
includes the password ("<roomID>:<password>") — without it the printed
room is not joinable, so the legacy roomID-only output was effectively
broken for the gen flow.

Lay the groundwork for splitting service-specific logic (WB / Jazz /
Telemost API flows) from wire-level transport engines (LiveKit, Goolom,
future Jitsi). An engine takes only URL+Token+Name+network knobs; an
auth provider produces those credentials and reports which engine it
feeds. RoomCreator is an optional capability for the gen mode.
Existing carriers and providers are untouched.
