Refactor T3 Moving Average Implementation and Remove Unused Tests

Browse Source 
- Deleted DebugTulip.Tests.cs as it was no longer needed.
- Refactored T3.cs to encapsulate parameters in a struct for better organization and readability.
- Updated methods in T3.cs to use the new Parameters struct, improving clarity and reducing redundancy.
- Enhanced T3.md documentation to provide clearer explanations of the T3 moving average and its parameters.
- Removed Wma.Coverage.Tests.cs as it was obsolete.
- Added new tests in IndicatorExtensions.Tests.cs to validate logic methods and ensure correct calculations.
- Updated IndicatorExtensions.cs to improve method organization and add new functionality for handling chart coordinates.
- Refactored mocks in TradingPlatformMocks.cs to align with new chart interface definitions.
