fix(accounts): unify modal width, add notify props to create, fix quota layout

- EditAccountModal width changed from "normal" to "wide" (match CreateAccountModal)
- CreateAccountModal now passes all quota notify props to QuotaLimitCard
- QuotaLimitCard: when global notify disabled, hide title row, input takes full width
- Quota alert email: show remaining quota + threshold (fixed/$, percentage/%) instead of usage trigger point
