Replace hardcoded URL mappings with dynamic algorithmic approach

- Build URL-to-filepath mapping dynamically from flexdown_docs list
- Eliminate 40+ hardcoded string replacements for maintainability
- Use algorithmic conversion based on actual docs folder structure
- Maintain compatibility with both StringVar and regular string handling
- Handle index files correctly: both /folder/ and /folder/index/ map to index.md
- All 245 documentation URLs continue to return 200 OK

Addresses GitHub comment from Alek99 about avoiding hardcoded values
in convert_url_path_to_github_path() function.
