feat(ui): add Web UI Enhancement with live training monitor, enhanced metrics, chat upgrade, and config builder (v0.24.2)

Part A: Training Live Monitor — SSE log streaming (/api/train/logs with Last-Event-ID reconnection), live metrics SSE (/api/train/metrics/live), progress endpoint (/api/train/progress), frontend with auto-scroll log panel, progress bar, and live indicator badge. Part B: Enhanced Metrics & Eval Display — 2x2 chart grid (loss, LR, grad_norm, throughput) + GPU memory chart, eval results table in run detail modal, /api/runs/compare endpoint (max 5 runs). Part C: Chat Upgrade — /api/chat/send SSE proxy with SSRF protection (localhost-only HTTP, HTTPS for remote), streaming via ReadableStream, typing indicator, cancel button, markdown renderer (bold/italic/code), chat settings panel (temperature/max_tokens/top_p/system prompt/adapter), chat export as JSON. Part D: Visual Config Builder — /api/config/schema (Pydantic field metadata extraction), /api/recipes (29 ready-made configs as JSON), /api/config/from-form (form values to validated YAML), recipe dropdown. Security: Chat proxy SSRF validation, max_tokens cap 16384, temperature 0-2, top_p 0-1, Bearer auth on POST, XSS prevention, compare max 5 runs. Tests: 58 new tests across 4 files (2128 total, 78 files), 67% coverage.

 **Security (v0.10.10+):** The Web UI generates a random auth token at startup (printed to console). All mutating endpoints (start/stop training, delete runs, inspect data, validate config) require `Authorization: Bearer <token>` header. CORS is restricted to the served origin. Data inspection is sandboxed to the working directory.
