Changelog: v3.0 Update

1. UX Improvement: Unified Dark Theme
   Removed Light Mode: To ensure consistent readability and accessibility, the app now enforces a unified Dark Theme.
   Fix: This resolves the reported contrast issue (white text on light background) in the “Quick Estimator” and ensures all text is clearly visible on all devices.
2. Smart Error Detection (Reverse Calculator)
   Added “ESA Lock” Warning: Previously, users who entered ESA marks in the Subjects tab thought the Reverse Calculator was broken or “stuck loading” because it couldn’t calculate a score that was already entered.
   New Feature: The app now automatically detects if ESA marks are present. It displays a prominent alert explaining that these subjects are “Locked” and instructs the user to clear the ESA mark if they want a prediction for that subject.
   Removed Loading Animation: Removed the spinning dice animation to prevent confusion about the app’s status.
3. Performance & Stability
   Optimized layout for mobile viewports.
   Improved input validation to prevent invalid calculations.

“Regarding the previous feedback on the ‘Reverse Calculator waiting time’: The delay was actually caused because ESA marks were entered in the Subjects tab, which ‘locks’ the calculation. I have added a Smart Warning System that now explicitly tells the user to remove ESA marks if they want a calculation, so it is impossible to get stuck now. I also removed Light Mode entirely to fix the contrast bug you found.”
