Make `STATUS_PAGE` configurable via environment variables

[ElvisKrop]

What is the feature about

Currently, the STATUS_PAGE URL is hardcoded in the IndexingStatus component. To improve flexibility and allow easier environment-specific customization (e.g., for staging, self-hosted deployments, or whitelabelled environments), it would be beneficial to move this constant to the central constants.ts configuration file and make it loadable via environment variables, with a fallback to the default https://status.safe.global.

The list of requirements

• Move const STATUS_PAGE from apps/web/src/components/sidebar/IndexingStatus/index.tsx to apps/web/src/config/constants.ts.
• Load the value of STATUS_PAGE from an environment variable (e.g., NEXT_PUBLIC_SAFE_STATUS_PAGE_URL).
• Fallback to https://status.safe.global if the environment variable is not defined.

Designs/sketches

N/A — this is a config/code-only change.

🛠️ Summary

This PR moves the STATUS_PAGE constant from the IndexingStatus component to the centralized constants.ts file and makes it environment configurable. This enables flexible deployment configurations (staging, self-hosted, white-labeled environments).

🔧 Changes

• STATUS_PAGE is now loaded from process.env.NEXT_PUBLIC_SAFE_STATUS_PAGE_URL
• Default fallback is set to https://status.safe.global
• Refactored usage in apps/web/src/components/sidebar/IndexingStatus/index.tsx
• Updated constants.ts to include the new STATUS_PAGE export

📦 Environment Variable

To override the default in a custom environment, set:
