feat:實作預約系統 — 時段管理、預約生命週期與前端整合

後端： - 新增 course_schedules / bookings migration（含索引） - BookingStatus / ScheduleStatus PHP BackedEnum - CourseSchedule / Booking Model（七狀態機 VALID_TRANSITIONS） - ScheduleController、ProviderBookingController、MemberBookingController - 雙層名額驗證（API 層快速失敗 + DB lockForUpdate 防超賣） - 24h 取消截止、pending 不佔位設計 - ExpirePendingBookings（每小時）/ CompleteFinishedBookings（每日）Scheduler - Docker cron 配置、CACHE_STORE 改為 file 修正 502 前端： - 課程詳情頁加入時段選擇與預約流程 - 我的預約頁（展開式卡片、狀態說明、連結課程詳情） - Coach 時段管理（上午/下午時間選擇器、新課程引導） - Coach 預約管理（依課程分組、待確認徽章） - Navbar 新增「我的預約」與「時段/預約管理」入口 - 密碼格式提示與即時比對 OpenSpec： - booking-system change 歸檔至 archive/2026-05-12-booking-system - 新增 specs/course-scheduling 與 specs/booking-lifecycle 主規格 Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
