♻️ refactor(StyleContext): modernize context architecture and eliminate route transition flicker

## Breaking Changes
- Remove backward compatibility layer for old action types
- StyleContext is no longer exported, use useStyle hook instead

## Major Improvements
- **Architecture**: Replace useState with useReducer for complex state management
- **Performance**: Add debounced resize handling and batch updates via BATCH_UPDATE action
- **DX**: Export useStyle hook and styleActions for type-safe usage
- **Memory**: Use useMemo to cache context value and prevent unnecessary re-renders

## Bug Fixes
- **UI**: Eliminate padding flicker when navigating to /console/chat* and /console/playground routes
- **Logic**: Remove redundant localStorage operations and state synchronization

## Implementation Details
- Define ACTION_TYPES and ROUTE_PATTERNS constants for better maintainability
- Add comprehensive JSDoc documentation for all functions
- Extract custom hooks: useWindowResize, useRouteChange, useMobileSiderAutoHide
- Calculate shouldInnerPadding directly in PageLayout based on pathname to prevent async updates
- Integrate localStorage saving logic into SET_SIDER_COLLAPSED reducer case
- Remove SET_INNER_PADDING action as it's no longer needed

## Updated Components
- PageLayout.js: Direct padding calculation based on route
- HeaderBar.js: Use new useStyle hook and styleActions
- SiderBar.js: Remove redundant localStorage calls
- LogsTable.js: Remove unused StyleContext import
- Playground/index.js: Migrate to new API

## Performance Impact
- Reduced component re-renders through optimized context structure
- Eliminated unnecessary effect dependencies and state updates
- Improved route transition smoothness with synchronous padding calculation
