fix extension registry stable order

[kulmann]

Description

While reviewing opencloud-eu/web-extensions#166 we found out that the order of applications during application loading is not stable. Instead of coming up with a sorting/weight concept we've decided to just maintain a stable order. This PR does that with the least possible performance impact:

• loading application scripts happens in parallel
• only building and registering the applications happens one by one, with the order defined by the config.json (this ran in parallel before, but produced a random order)
• calling the initialize hook on all applications happens in parallel again

How Has This Been Tested?

Manually and with the existing unit tests.

Types of changes

• Bugfix
• Enhancement (a change that doesn't break existing code or deployments)
• Breaking change (a modification that affects current functionality)
• Technical debt (addressing code that needs refactoring or improvements)
• Tests (adding or improving tests)
• Documentation (updates or additions to documentation)
• Maintenance (like dependency updates or tooling adjustments)

Pull Request Overview

This PR fixes the extension registry ordering issue by ensuring applications are loaded and registered in a stable order. The change separates the loading phase (which remains parallel for performance) from the building/registration phase (which now happens sequentially to maintain order).

Key changes:

• Split application handling into separate loadApplication and buildApplication functions
• Application script loading remains parallel but building/registration now happens sequentially
• Application initialization continues to run in parallel after all apps are built
