feat: implement comprehensive Period Management Framework (issue #112)

Complete period lifecycle management system including:

- PeriodManager class with full lifecycle operations
- Period status management (open/calculating/closed) with validation
- Period overlap detection and conflict resolution
- Comprehensive cost calculation and aggregation engine
- Loss carried forward calculations between periods
- Period closure validation with audit trails
- Current period detection and auto-creation utilities

CLI Integration:
- Complete period command suite (create, list, show, calculate, status, close, current)
- Professional CLI output with detailed formatting
- Comprehensive error handling and validation
- Date filtering and status filtering capabilities

Testing:
- 25 core PeriodManager tests covering all functionality
- 24 CLI command tests ensuring proper integration
- Edge case testing for complex scenarios
- 49 total tests passing with comprehensive coverage

Database Integration:
- Utilizes existing cost_periods schema from FinanceModels
- Full SQLite integration with proper constraints
- Performance-optimized indexes and queries
- Seamless integration with existing cost tracking system
