prefixComposables in options is obsolete since nuxt 4.5 introduced useLayout

[janheussner]

Problem / motivation

After upgrading my project to Nuxt 4.5 I was realizing that Nuxt has introduced a useLayout composable. Means with the prefixComposables: false you are always running in a conflict.

Proposed solution

prefixComposables has to be always true by default for versions >= nuxt 4.5 and can be completly removed in the future.
