ResolvePayeeFlagRequest

Resolve a bank-analysis ``uncategorised_leg`` review flag: route a payee to a category. Persisted as durable (workspace, client)-scoped precedent so the next cycle auto-applies it and re-emits zero flags for that payee.

Field	Type	Description
`payee_token`required	`string`	Distinctive payee token to route (e.g. 'GRAVITA'); upper-cased on store.
`category`required	`string`	Engine category key the payee's legs route to (e.g. 'acct', 'mgmt').
`direction`	`string \| null`	'dr' (payments only), 'cr' (receipts only), or null (either direction).
