fix(apps): filter autoloading registration by app type in loadApps

[joshtrichards]

Summary

Make loadApps(array $types = []) apply the $types filter consistently to both code paths.

Previously, the initial autoloader-registration loop ignored $types and touched all enabled apps, while the later loadApp() loop only loaded matching app types. Since loadApp() already handles autoloader registration itself, this broad pre-registration was inconsistent with the method contract and appears redundant for filtered loads. PHP CI also passed with the $types filter applied.

Context

I couldn’t find evidence that loadApps() must pre-register autoloaders for non-target app types; loadApp() and Coordinator already register autoloading per app. At best, this looks like historical baggage rather than part of the documented contract.

To stay conservative in case there are hidden cross-app assumptions (that aren't already addressed in other ways), this change only applies the $types filter to the first loop for now, rather than removing that loop entirely.

Testing

• PHP CI passed with the $types filter applied to the autoloader-registration loop.

Notes

• This appears safe for both IBootstrap and non-IBootstrap apps.
• Possible follow-up: remove the remaining redundant pre-registration loop entirely.
