Fix CI: remove path filters that don't match standalone repo structure

- Remove 'paths' filter from push/pull_request triggers
- Path filters like 'botui/**' only work in main gb repo
- In standalone botui repo, files are at root level (src/, Cargo.toml, etc.)
- CI will now run on all pushes to main branch
