refactor: migrate to directory-based stack structure

- Updated ComposeService to run docker commands from stack-specific directories, ensuring relative paths resolve correctly.
- Refactored FileSystemService to manage stacks as directories, including methods for creating, updating, and deleting stacks.
- Implemented automatic migration of existing flat-file stacks to the new directory structure on server startup.
- Adjusted API routes to use stack names instead of filenames, simplifying stack management.
- Modified frontend components to align with the new stack naming conventions and removed unnecessary file extensions.
