Balances: Vault / user / address

A single balances endpoint. A balance is an aggregation of ledger accounts (available: can be spent; reserved: locked by pending transfers but still belongs to the owner). Balances are a denormalization of the double-entry journal and are updated atomically with the entries.

ISOLATION: a user sees balances ONLY for their own addresses; an admin sees the entire Vault. Filters: ?addressId= (your own address), ?token=, ?summary=true (totals only, for the dashboard), ?purpose= (filters the account list; totals always include the available/reserved breakdown). Vault-level accounts (external/adjustment) aren't included in totals.
