Remove manual name update logic from tool_service.py

[rakdutta]

The name field is now a calculated field and should not be manually updated.
This PR removes the redundant code block in tool_service.py that previously handled name updates:

if tool_update.name is not None:
    tool.name = tool_update.name

Key Changes

• Removed explicit name assignment during tool update.
• Ensures consistency by relying only on calculated logic for the name field.
• Prevents unintended overwrites of the computed name.
