The quota reset mechanism is lazy — quota_daily_used/quota_weekly_used
in the database are only reset on the next IncrementQuotaUsed call.
The scheduling layer (IsQuotaExceeded) correctly checks period expiry
before enforcing limits, so the account remains usable. However, the
API response mapper reads the raw DB value without checking expiry,
causing the frontend to display cumulative usage (e.g. 110%) even
after the reset period has passed.

Add IsDailyQuotaPeriodExpired/IsWeeklyQuotaPeriodExpired methods and
use them in the mapper to return used=0 when the period has expired.

Align struct field assignments and fix indentation detected by
golangci-lint v2.9's gofmt checker.

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

- Add configurable spending limit (quota_limit) for apikey-type accounts
- Atomic quota accumulation via PostgreSQL JSONB operations on TotalCost
- Scheduler filters out over-quota accounts with outbox-triggered snapshot refresh
- Display quota usage ($used / $limit) in account capacity column
- Add "Reset Quota" action in account menu to reset usage to zero
- Editing account settings preserves quota_used (no accidental reset)
- Covers all 3 billing paths: Anthropic, Gemini, OpenAI RecordUsage

chore: bump version to 0.1.90.4

新增 UMQ (User Message Queue) 双模式支持:

- config: 新增 Mode 字段，保留 Enabled 向后兼容
- service: 新增 UserMessageQueueService（Lua 锁/延迟算法/清理 worker）
- repository: 新增 UserMsgQueueCache（Redis Lua acquire/release/force-release）
- handler: 新增 UserMsgQueueHelper（SSE ping + 等待循环 + throttle）
- gateway: 按 mode 分支集成 serialize/throttle 逻辑
- lint: 修复 gofmt rewrite rules、errcheck 类型断言、staticcheck QF1012

前端:
