Paul Rastoin ebe816abb5 Remove outdated index view pitfall from app agent docs (#23667)
## Context

Index views are now auto-generated by a metadata side effect when an
object is created, so the "Common Pitfalls" entry warning against
creating an object without an associated index view is obsolete.

## What changed

Removed the line "Creating an object without an index view associated.
Unless this is a technical object, user will need to visualize it."
from:

- the `create-twenty-app` template
(`packages/create-twenty-app/src/constants/template/AGENTS.md`), used
for newly scaffolded apps
- the 14 existing copies across `packages/twenty-apps` (`AGENT.md` /
`AGENTS.md` / `CLAUDE.md` / `LLMS.md` in `examples`, `public`, and
`internal` apps)

The other pitfalls (navigationMenuItem, front-component scroll) are
unchanged since they still apply.
