Refactor HealthCheck: Improve storage checks and add Cloudflare cache handling

[Cyrus-Sushiant]

Description

We need to refactor the current Healthcheck implementation in the Boilerplate project to improve reliability and clarity, especially around storage validation and caching behavior.

---

Problems

Currently, the Healthcheck logic has a few limitations:

1. Storage handling is unclear and split without proper abstraction

   • We have two separate storage systems:

     • One used for storing profile pictures
     • Another used for checking the project’s bin directory

   • These are currently handled in a way that is not clearly separated or well-structured.

2. No unified storage health strategy

   • There is no clear interface or abstraction layer to handle different storage types consistently.

3. Cloudflare caching is not considered in healthcheck

   • Healthcheck responses may be cached by Cloudflare.
   • This can lead to false positives or outdated health status being served.
