Subject: [PATCH] Fix JSON serialization error in get_installed_apps()

Skip non-serializable VERSION attributes when building the installed
apps dictionary for /api/status/. Some packages using setuptools-scm
define VERSION as a type placeholder (e.g., `object`) at runtime rather
than an actual version tuple or string, causing "Object of type type is
not JSON serializable" errors.

This change adds a check to skip any VERSION value that is neither a
tuple nor a string, preventing serialization failures while still
correctly handling standard version formats.
