fix: disable homepage caching in local development environment

[KrishnaShuk]

Closes #12324

Fix

Disables the 5-minute homepage Memcache in local dev environments so template changes reflect instantly upon refresh.

Technical

Conditionally bypasses get_cached_homepage() in home.py when the "dev" feature flag is detected.

Testing

1. Modify any string in templates/home/index.html.
2. Refresh the homepage; changes should appear immediately without a container restart.

Pull request overview

Disables homepage memcache caching in local development ("dev" feature flag) so homepage template/content changes show up immediately on refresh, while keeping the existing 5-minute caching behavior for non-dev environments.

Changes:

• In home.GET(), bypasses get_cached_homepage() when "dev" in web.ctx.features and calls get_homepage() directly.
• Keeps the existing cached homepage path unchanged for non-dev environments.

Very good job on this one! Good eye catching that we need to specify dev mode and you used modern python syntax 👍
