[feature logging] Feature FMEA creation

## What

Create the Feature FMEA (`wp__feature_fmea`) for the feature logging. The FMEA verifies the feature architecture as part of the SW Safety Concept, linking detections, preventions, and mitigations to Feature Requirements or Assumptions of Use.

## How

**Process step:** [wf__analyse_featarch](https://eclipse-score.github.io/process_description/main/process_areas/safety_analysis/safety_analysis_workflow.html#wf__analyse_featarch)

## Definition of Done

All criteria of the [Safety Analysis Checklist](https://eclipse-score.github.io/process_description/main/process_areas/safety_analysis/guidance/safety_analysis_checklist.html) are met.

## Template & Folder Structure

- **Template:** [Feature FMEA Template](https://eclipse-score.github.io/module_template/main/docs/features/feature_example/safety_analysis/fmea.html)
- **Folder:** `docs/features/logging/safety_analysis/` – see [Module Folder Structure](https://eclipse-score.github.io/module_template/main/index.html#module-layout)

*Please apply the linked template and folder structure to ensure consistency across the S-CORE project.*

Start with the Feature FMEA Template and the wf__analyse_featarch process step linked in the issue. Create the artifact under docs/features/logging/safety_analysis/ using the stated module folder structure, then check the Safety Analysis Checklist to verify completion and confirm that detections, preventions, and mitigations link to Feature Requirements or Assumptions of Use.
