Fix TypeScript import detection for files with dots in name

Fixed issue where TypeScript files with dots in their names (e.g., abstract.helper.ts) were not being detected and transpiled when imported without extension. The problem was that path.extname() would consider the last dot as a file extension.

Now the transpiler:
- Checks if an import has a standard module extension (.js, .mjs, .cjs, .json, .node)
- If not, tries adding .ts extension to find and transpile TypeScript files
- This correctly handles files like abstract.helper.ts, material.component.helper.ts, etc.

Added test case to verify this scenario works correctly.
