feat: enable $ binding inside ::attrs with proper render order

- Apply renderTemplate before assigning DOM attributes
- Fix $ state binding for input value, placeholder, boolean attrs
- Normalize attrs handling across properties and attributes
- Complete attrs rendering pipeline in NeoCore

This enables reactive attribute binding using $ syntax
and fixes incorrect raw value assignment.
