[WIP] Update resource-providers module to follow style guide

[Copilot]

• Explored repository structure and understand current state
• Examined style guide requirements and identified violations
• Analyzed current source code files for style compliance

Style Guide Violations Identified:

1. Public class missing final modifier

• Fix AppServerResourceDetector class - should be final as it's a public non-internal class

2. Static imports cleanup

• Review and add appropriate static imports for commonly used methods/constants

3. Class organization issues

• Review class field/method organization in nested classes like ResourceLocatorImpl

4. Field final modifier opportunities

• Review fields that could be marked final

The module currently builds successfully and passes all tests. Formatting is already correct per spotlessCheck.

Fixes #280.
