CG-12125: Fix TSCodeBlock missing end_byte_for_condition_block attribute

[codegen-sh]

Description

This PR fixes the cloud parse failure due to TSCodeBlock missing the end_byte_for_condition_block attribute.

Problem

The error occurs during dependency resolution in the resolve_name method in codegen/sdk/core/expressions/name.py. When resolving names in conditional blocks, it tries to access end_byte_for_condition_block on a TSCodeBlock object, but this attribute is not implemented for TSCodeBlock.

The error message is:

AttributeError: 'TSCodeBlock' object has no attribute 'end_byte_for_condition_block'

Solution

Added the end_byte_for_condition_block property to TSCodeBlock class, which simply returns the end_byte value, matching the default implementation in the ConditionalBlock interface.
