docs: move Docker documentation to wiki and clean references

- Remove DOCKER_STRATEGY.md and DOCKER_CHANGES.md from main repository
- Update CLAUDE.md to reference comprehensive Docker wiki documentation
- Clean up redundant Docker documentation in favor of centralized wiki
- Maintain quick usage examples while pointing to detailed wiki guide

All Docker documentation is now consolidated in the English wiki at:
https://github.com/JohanDevl/Export_Trakt_4_Letterboxd/wiki/Docker

+The project implements an intelligent Docker image management system with semantic versioning and automatic cleanup. For comprehensive Docker documentation including image strategy, compose profiles, and usage examples, see the [Docker Wiki](https://github.com/JohanDevl/Export_Trakt_4_Letterboxd/wiki/Docker).
 
-**Tagging Strategy:**
-- `latest` + `main` + `v1.2.3` for main branch (semantic versioning)
-- `develop` for develop branch
-- `PR-123` for pull requests (testing before merge)
-
-**Automatic Cleanup:**
-- PR images are deleted when PR is closed
-- Daily cleanup (2 AM UTC) removes obsolete images
-- Protected tags: `latest`, `main`, `develop`, semantic versions (`v*`), and active PR tags
-- Cleanup applies to both Docker Hub and GitHub Container Registry
-
-**Usage Examples:**
+**Quick Usage:**
 ```bash
 docker pull johandevl/export-trakt-4-letterboxd:latest    # Production
 docker pull johandevl/export-trakt-4-letterboxd:develop   # Development  
 docker pull johandevl/export-trakt-4-letterboxd:PR-123    # Test PR
