refactor: batch 3 — decompose CheckBalanceAfterDeduction, merge crossing checks, add QuotaNotifyConfig

M1: CheckBalanceAfterDeduction (63→18 lines) decomposed into:
    canNotifyBalance, resolveUserEffectiveThreshold, crossedDownward, dispatchBalanceLowEmail
M3: New Account.QuotaNotifyConfig(dim) method replaces 9 hardcoded getters
    (getters kept as thin wrappers for backward compatibility)
M4: checkQuotaDimCrossings + checkQuotaDimCrossingsFromState merged into one
    function taking pre-built []quotaDim; caller builds dims conditionally
