Add background job queue system for generation
- Implements sequential job queue with background worker thread (_enqueue_job, _queue_worker) - All generate routes now return job_id instead of prompt_id; frontend polls /api/queue/<id>/status - Queue management UI in navbar with live badge, job list, pause/resume/remove controls - Fix: replaced url_for() calls inside finalize callbacks with direct string paths (url_for raises RuntimeError without request context in background threads) - Batch cover generation now uses two-phase pattern: queue all jobs upfront, then poll concurrently via Promise.all so page navigation doesn't interrupt the process - Strengths gallery sweep migrated to same two-phase pattern; sgStop() cancels queued jobs server-side - LoRA weight randomisation via lora_weight_min/lora_weight_max already present in _resolve_lora_weight Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
