Not Enough Calculator

Fixes & Improvements:

• Settings GUI Fix (/calcconfig): Fixed /calcconfig command failing to open the settings screen in production builds by replacing non-remapped reflection string lookups with direct API calls.
• Escape Key & Exit Flow: Fixed Escape key and Cancel button handling so closing the settings menu when opened from chat returns players smoothly back to gameplay.
• Heuristics & Typing Detection: Expanded isExpressionComplete() heuristic regex in CalculatorManager to cover all 26 supported functions (bz, ah, ahbin, fmt, hex, bin, oct, rad, deg, etc.), preventing premature error popups while typing.
• Dependency & Version Updates: Updated target build for Minecraft 1.21.11 with updated Fabric API (0.141.6), REI (21.11.816), and ModMenu (17.0.1-beta.1).
