#9529 - Refactor: Remove unnecessary type assertions

[sonozyurt]

How the feature works? / How did you fix the issue?

This PR removes unnecessary type assertions across the codebase that do not change the expression type, addressing code quality issues identified by SonarQube.

Changes:

• Removed unnecessary as type assertions in actionmenu.tsx where the type was already correctly inferred
• Removed redundant type assertions in sdata.ts modal state management

These changes improve code clarity without affecting functionality, as the assertions were redundant (the compiler already knew the correct types).
