  - Merge "Support filtering portgroups by shard"
  - Support filtering portgroups by shard

    This was somehow missed during initial implementation. Adding ability to
    filter portgroup by shard. This was mostly vibe coded with claude, with
    me interupting to suggest better implementations when it did something
    silly. Tested manually by a human using fake drivers :).
