chore(compass-assistant): move the two appNameForPrompt values together

[lerouxb]

We might still change this further and just have two separate instructions prompts so we have more flexibility in editing them, but at least this puts what we have so far together.

Pull Request Overview

This PR refactors the compass assistant configuration by moving hardcoded app name strings to a centralized constant object. The change improves maintainability by consolidating the app name values used in assistant prompts into a single location.

• Introduces APP_NAMES_FOR_PROMPT constant object to centralize app name configurations
• Updates both Compass and Compass Web applications to use the centralized constants
• Exports the new constant from the compass-assistant package for wider usage
