Update coordinate system documentation to INCHES
Updated documentation and code comments to reflect INCHES as the coordinate unit instead of 1/100 inch. Replaced special characters causing issues with proper symbols (e.g., `—`, `≈`, `→`). - Updated VB.NET code snippet to clarify INCHES usage. - Revised `COPILOT_CONTEXT_EN.md` with updated formulas, unit comparison tables, and database storage format details. - Corrected XML documentation for `SignatureDto` and `AnnotationDto` in C# to reflect INCHES as the unit. - Clarified database schema documentation for coordinate fields. - Improved unit conversion quick reference with accurate formulas. - Added A4 page dimensions reference in multiple units. - Marked completed tasks in "Session 12 Changes Already Completed" with detailed descriptions.
