Introduce Pattern Template entity as a reusable rectangle layout that Key Colors targets reference via pattern_template_id. This replaces inline rectangle storage with a shared template system. Backend: - New PatternTemplate data model, store (JSON persistence), CRUD API - KC targets now reference pattern_template_id instead of inline rectangles - ProcessorManager resolves pattern template at KC processing start - Picture source test endpoint supports capture_duration=0 for single frame - Delete protection: 409 when template is referenced by a KC target Frontend: - Pattern Templates section in Key Colors sub-tab with card UI - Visual canvas editor with drag-to-move, 8-point resize handles - Background capture from any picture source for visual alignment - Precise coordinate list synced bidirectionally with canvas - Resizable editor container, viewport-constrained modal - KC target editor uses pattern template dropdown instead of inline rects - Localization (en/ru) for all new UI elements Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
