Implement foundation for live URL system with database schema, relations,
and comprehensive service layer for live scope management.
**Database Schema (Section 8.4):**
- **liveScopes table** with fields:
- id (UUID primary key)
- projectId (foreign key to projects, cascade delete)
- slug (text, unique within project)
- allowNewGenerations (boolean, default: true)
- newGenerationsLimit (integer, default: 30)
- meta (JSONB for flexible metadata)
- createdAt, updatedAt timestamps
- **Constraints & Indexes:**
- Unique constraint on (projectId, slug) combination
- Index for project lookups
- Index for project+slug lookups
- **Relations:**
- projects → liveScopes (one-to-many)
- liveScopes → project (many-to-one)
**Type Definitions:**
- Added LiveScope, NewLiveScope types from database schema
- Added LiveScopeWithStats interface with computed fields:
- currentGenerations: number (count of images in scope)
- lastGeneratedAt: Date | null (latest generation timestamp)
- images?: Image[] (optional images array)
- Added LiveScopeFilters interface for query filtering
**LiveScopeService:**
- **Core CRUD operations:**
- create() - Create new scope
- getById() - Get scope by UUID
- getBySlug() - Get scope by slug within project
- getByIdOrThrow() / getBySlugOrThrow() - With error handling
- update() - Update scope settings
- delete() - Hard delete scope (images preserved)
- **Statistics & Computed Fields:**
- getByIdWithStats() - Scope with generation count and last generated date
- getBySlugWithStats() - Same but lookup by slug
- list() - Paginated list with stats for each scope
- **Business Logic:**
- canGenerateNew() - Check if scope allows new generations
- createOrGet() - Lazy creation with project defaults
- Uses images.meta field for scope tracking (scope, isLiveUrl)
**Technical Notes:**
- Images track scope via meta.scope field (no schema changes to images table)
- Scope statistics computed from images where meta.scope = slug and meta.isLiveUrl = true
- Project settings (allowNewLiveScopes, newLiveScopesGenerationLimit) already added in Phase 2
- All code compiles with zero new TypeScript errors
