refactor: replace any types with proper TypeScript types

Improves type safety throughout the codebase by eliminating unsafe `any` type assertions and replacing them with proper type definitions.

Adds explicit type parameters and constraints to MMKV augmentations, component props, and router navigation calls. Updates function signatures to use `unknown` instead of `any` where appropriate, and properly types Icon glyphs, router Href parameters, and component prop spreads.

Enhances maintainability and catches potential type errors at compile time rather than runtime.
