feat: enable verbatimModuleSyntax in TypeScript config (#5533)

## Summary
- Enable `verbatimModuleSyntax` compiler option in TypeScript
configuration
- Update all type imports to use explicit `import type` syntax
- This change will Improve tree-shaking and bundler compatibility

## Motivation
The `verbatimModuleSyntax` option ensures that type-only imports are
explicitly marked with the `type` keyword. This:
- Makes import/export intentions clearer
- Improves tree-shaking by helping bundlers identify what can be safely
removed
- Ensures better compatibility with modern bundlers
- Follows TypeScript best practices for module syntax

## Changes
- Added `"verbatimModuleSyntax": true` to `tsconfig.json`
- Updated another 48+ files to use explicit `import type` syntax for
type-only imports
- No functional changes, only import/export syntax improvements

## Test Plan
- [x] TypeScript compilation passes
- [x] Build completes successfully  
- [x] Tests pass
- [ ] No runtime behavior changes
