What happened?

In system/Cache/Handlers/FileHandler.php, inside the getItem() method, the call to file_get_contents() can return false, which currently leads to a fatal error that crashes the application without any explanatory message. It would be preferable to:

Detect when file_get_contents() returns false.
In that case, ignore the cached file and regenerate the cache entry.
Emit a clear warning to the console indicating that reading the cache failed, so developers aren’t left with a silent crash.

Steps to Reproduce

1. Make cache unreadable (for example, no permissions)
2. Try to get it

Expected Output

Warning or error in console, no crash, recalculate of cache

Anything else?
