Use built-in pagination instead of paginator - #70
Conversation
Switch _deleteChunksPage to ctx.db.query(...).paginate(), restarting from the beginning when given an old paginator-format cursor. Drop the convex-helpers dependency and temporarily install convex-test from pkg.pr.new (convex-test#163).

💡 Result:
Convex’s built-in `.paginate()` **does not work inside components** because of how Convex tracks reactive pagination. The authoring guide recommends using `paginator` from `convex-helpers` instead. If exposing pagination for React, it also recommends `usePaginatedQuery` from `convex-helpers` rather than `convex/react`.

Do not use built-in .paginate() until component support is available.
_deleteChunksPage is an internal mutation in the component. The Convex component guide states that built-in .paginate() does not work inside components. deleteStream deletes the stream before scheduling _deleteChunksPage, so a rejected pagination call leaves its chunk rows behind. Keep the convex-helpers paginator until the required backend release is deployed, or gate this change on that support.

Removed the now-unusedpaginatorandschemaimports.[(from a deletion scheduled before this deploy) is treated asnull.
