ledger: drop stale 'SurrealQL' as the deferred forward target

The D-ATC2-KAUSAL-RUFF-GATED debt note echoed SPEC-ATC2-OGAR §6's stale
'SurrealQL-Adapter' wording. Per the operator ruling already in this ledger
(2026-07-05: 'Odoo's spog lives now in V3 substrate in lance-graph <>OGAR,
not surrealdb AST'), the forward substrate is OGAR-v3 / lance-graph; the
SurrealQL-AST adapter is deprecated. The live emitter debt is the TTL path
(ogar-emitter → ogar-adapter-ttl + v3 substrate), not SurrealQL.
