Redirect condition in PaginatedJsonRequesterHandler is always true

[SeanTAllen]

`paginated_list.pony:236` has:

elseif (_status != 301) or (_status != 307) then

This is always true — for any value of `_status`, at least one of the two comparisons will be true. It should be `and`:

elseif (_status != 301) and (_status != 307) then

The same bug existed in `http_get.pony:108` (noted in CLAUDE.md). The new search pagination code in the `search-pagination` branch already uses the correct `and` logic.

Fixed in #53 (commit 7ed8dc0). All three locations (http_get.pony, paginated_list.pony, search.pony) now use and instead of or.
