Micro: Enhance hook documentation with JSDoc

[Copilot]

This micro PR adds comprehensive JSDoc documentation to the useDoseCalculator hook in lib/hooks/useDoseCalculator.ts. The hook is a critical component managing dose calculation workflows but lacked proper documentation, making it difficult for developers to understand its complex functionality.

Changes Made

Main Hook Documentation

• Added detailed JSDoc block for the useDoseCalculator function explaining its comprehensive responsibilities
• Documented all parameters with clear descriptions and types
• Provided detailed return value documentation covering all exposed state and handlers
• Included practical usage examples demonstrating common patterns

Type and Interface Documentation

• Added JSDoc comments for all key types: ScreenStep, ManualStep, Syringe, ResetFullFormFunc
• Enhanced UseDoseCalculatorProps interface with parameter descriptions
• Documented utility functions like isValidValue

Documentation Highlights

The documentation now clearly explains that this hook manages:

• Screen navigation and step management for scan and manual entry workflows
• Form validation and error handling across multiple medication input types
• Dose calculation logic with various medication formats
• Integration with camera scanning, analytics, logging, and user experience features
• Complex modal states for errors, promotions, and user feedback

Code Quality

• No functional changes made - purely documentation enhancement
• All existing tests continue to pass
• ESLint shows no new warnings or errors
• Maintains existing code patterns and structure

The hook now provides clear guidance for developers working with this complex component, improving code maintainability and reducing onboarding time for new team members.

Fixes #378.
