fix(modules): prevent ISR from caching 404 error responses

[YoSoySergio]

Resolves #2148, #2140

Problem

The /modules page intermittently returns 404 errors when accessed directly. The issue occurs because:

1. The page uses ISR with 1-hour cache
2. When queryCollection('landing').path('/modules') transiently fails, a 404 is thrown
3. ISR caches the 404 response, causing persistent failures until cache expires

Solution

Set Cache-Control and CDN-Cache-Control headers to no-store before throwing the 404 error, preventing ISR from caching the error response.
