fix: return page as object {page, next, total, hasMore, nextUrl} for routes.js compat

routes.js reads resp.page?.hasMore and resp.page?.nextUrl — the old
HTTP client returned page as an object from parsePageInfo. The CLI
pivot accidentally returned page as a number, making hasMore always
undefined in routes.js. Restore the object shape in both gitea and
gitlab clients. Update tests to assert the object shape.
