standardise on --label; add label filter and display to pr list/view

- rename --hashtag (comma-separated) to --label (repeatable) on issue list,
  matching the --label flag already used on issue create
- add --label filter to pr list with the same OR semantics (matching GitHub)
- display labels column in pr list table and Labels: line in pr view
- include labels array in all JSON outputs (list and view for both issue and pr)
- rename internal 'hashtags' -> 'labels' throughout issue_list.rs and list.rs
