Completes the #985/#986/#987 caller sweep: categorize-core, v1
batch-categorize, pending-operation edits and the MCP categorize path now
resolve the settlement leg from the transaction's cash account instead of
inheriting a hardcoded or stale account. Extends the correct_entry preview
with currency, tax and dimension line metadata so staged corrections
preserve full line fidelity. Adds a read-only audit query and a runbook for
reviewing and correcting historical mis-bookings via staged storno with
explicit approval; no automated bulk mutation.
Fixes#1001
