[Improvement] Check number of operations vs Guarantee upon accept
requested to merge KKsurendran06/etir-national-application:fix/check-operations-vs-guarantee into dev-1.0.3
Shows the calculated operation count when accepting a guarantee and displays a separate warning when planned operations exceed the guarantee maximum. Accept remains enabled. Tested with backend summary tests, frontend tests, ESLint, production build, and live Union-mode fixtures.
