feat(account): add daily/weekly periodic quota limits for API Key accounts

Extend the existing total quota limit with daily and weekly periodic
dimensions. Each dimension is independently configurable and uses lazy
reset — when the period expires, usage is automatically reset to zero on
the next increment. Any dimension exceeding its limit will pause the
account from scheduling.

Backend:
- Add GetQuotaDailyLimit/Used, GetQuotaWeeklyLimit/Used, HasAnyQuotaLimit
- Rewrite IncrementQuotaUsed with atomic CTE SQL for 3-dimension update
- Rewrite ResetQuotaUsed to clear all dimensions and period timestamps
- Update postUsageBilling to use HasAnyQuotaLimit()
- Preserve daily/weekly used values on account edit

Frontend:
- Refactor QuotaLimitCard from single v-model to 3-dimension props
- Add QuotaBadge component for compact D/W/$ display
- Update AccountCapacityCell with per-dimension badges
- Update Create/Edit modals with daily/weekly quota fields
- Update AccountActionMenu hasQuotaLimit to check all dimensions
- Add i18n strings for daily/weekly/total quota labels
