Add VR controller remapping configuration system

Implement comprehensive controller remapping UI that allows users to customize
VR controller button and stick mappings with per-axis granularity and inversion
controls. Configuration persists to localStorage and applies on level start.

## Features
- Full-page controller remapping UI at #/controls
- Per-axis stick mapping (4 dropdowns: leftX, leftY, rightX, rightY)
- Individual axis inversion toggles (8 total invert options)
- Button remapping (6 buttons: trigger, A, B, X, Y, squeeze)
- Available actions: yaw, pitch, roll, forward thrust, camera, status screen
- Configuration validation with warnings for duplicates/missing controls
- Preview/test functionality to review current mapping
- Reset to default option
- localStorage persistence with backward compatibility

## Implementation
- ControllerMappingConfig singleton manages configuration and validation
- ControlsScreen handles UI logic and form manipulation
- ControllerInput applies mapping by translating raw input to actions
- Actions mapped back to virtual stick positions for ShipPhysics
- No changes needed to ShipPhysics - receives correctly mapped values

## User Flow
1. Navigate to Controls via header menu
2. Select action for each stick axis (yaw/pitch/roll/forward/none)
3. Toggle invert checkboxes as needed
4. Assign button actions (fire/camera/status/none)
5. Save configuration
6. Changes apply when starting new level

## Technical Details
- Storage key: 'space-game-controller-mapping'
- Raw stick values stored, mapping applied in getInputState()
- Supports future actions without code changes
- Validation ensures critical controls (fire, forward) are mapped
