Description

On an App LLM Proxy's Guardrails & Policies tab, clicking Add under Global Guardrails & Policies opens a catalog panel with a Categories filter (defaulting to AI). Under that default filter, Word Count Guardrail never appears — not by scrolling, and not by typing its name into the search box.

Root cause: the panel fetches the catalog with a hardcoded limit=40. The AI category currently has 43 policies, returned alphabetically, so the last 3 — Token Based Ratelimit, URL Guardrail, Word Count Guardrail — fall past the cutoff and are silently dropped. The search box only filters the already-fetched 40 items client-side, so it can never surface one that didn't make the batch, no matter what's typed.

Suggested fix:

• Wire the search box to the catalog API's own search param (server-side), instead of filtering the already-fetched page client-side.
• Add pagination: load the next page via the API's existing offset support as the user scrolls to the bottom of the list (infinite scroll), instead of a one-shot capped fetch — so no category is silently truncated regardless of how large it grows.

Steps to Reproduce

1. On any App LLM Proxy, go to Guardrails & Policies → Add (under Global Guardrails & Policies).
2. Leave Categories on the default AI filter.
3. Search Word Count, or scroll the full list — no result; the list ends at "Time-Based Model Routing".
4. Switch Categories to Guardrails instead — Word Count Guardrail now appears.
