feat: add repo-level filter to issues and pulls list views

Add a repo dropdown to the filter bar that appears when an org is
selected. The dropdown lists all repos in the selected org and
filters issues/pulls to the chosen repo. Changing the org resets
the repo filter. Infinite scroll preserves the repo filter.

Closes leeworks-agents/gitea-mobile#83
