feat: add Sora admin backend and fix type inconsistencies

Backend changes:
- Add SoraHandler for admin Sora management APIs
  - GET /api/v1/admin/sora/stats - system statistics
  - GET /api/v1/admin/sora/users - user storage stats
  - GET /api/v1/admin/sora/generations - generation records
  - DELETE /api/v1/admin/sora/users/:id/storage - clear user storage
- Add sora_storage_quota_bytes to AdminUser DTO
- Add SoraStorageQuotaBytes to UpdateUserInput for admin user updates
- Add comprehensive tests for SoraHandler

Frontend changes:
- Add soraAdminAPI for Sora management
- Add sora_storage_quota_bytes and sora_storage_used_bytes to AdminUser type
- Add Sora storage quota field to UserEditModal (GB unit)
- Fix UsageLog type: add media_type, fix duration_ms to optional
- Fix AdminUsageLog type: add channel_id, billing_tier

Test fixes:
- Add window.matchMedia mock to AccountUsageCell.spec.ts
- Add tlsFingerprintProfileAPI mock to EditAccountModal.spec.ts
- Fix loadTLSProfiles function order in EditAccountModal.vue
- Fix translation key references in AccountStatusIndicator.spec.ts
