feat: add label filter to issues and pulls list views

Add a label text input to the filter bar on both issues and pulls
list views. The filter is passed through to the Gitea API's native
labels query parameter for server-side filtering. Infinite scroll
preserves the label filter across page loads.

Closes leeworks-agents/gitea-mobile#82
