fix(dev-preview): address code review issues

- Use get_logger() from src.logging_config instead of logging.getLogger()
  in visual_display_manager.py to match project logging conventions
- Eliminate duplicate public/private weather draw methods — public draw_sun/
  draw_cloud/draw_rain/draw_snow now delegate to the private _draw_* variants
  so plugins get consistent pixel output in tests vs production
- Default install_deps=False in dev_server.py and render_plugin.py — dev
  scripts don't need to run pip install; developers are expected to have
  plugin deps installed in their venv already
- Guard plugins_dir fixture against PermissionError during directory iteration
- Fix PluginInstallManager.updateAll() to fall back to window.installedPlugins
  when PluginStateManager.installedPlugins is empty (plugins_manager.js
  populates window.installedPlugins independently of PluginStateManager)
- Remove 5 debug console.log statements from plugins_manager.js button setup
  and initialization code
