Replace custom canvas save/load with built-in save_load_adapter

- Remove custom canvas selector UI (HTML popup, CSS styles, toolbar button)
- Remove all custom canvas JS functions (toggleCanvasSelector, loadCanvas,
  saveCanvas, autoSaveCanvas, startAutoSave, newCanvas, deleteCanvas, etc.)
- Add createSaveLoadAdapter() implementing TradingView's save_load_adapter:
  - Chart layouts: localStorage index + backend API storage (no backend changes)
  - Study/Drawing/Chart templates: pure localStorage
- Enable load_last_chart and auto_save_delay in widget config
- Add DEV_MODE auth bypass for localhost development
- Update auth-config.js with production API URL and OAuth client ID
- Update README.md and README_CN.md feature descriptions
