fix: Devtools timeline breaks function key injection

[cernymatej]

🐛 The bug

When devtools.timeline.enabled is set to true, composables that rely on automatic key injection (useState, callOnce) fail at runtime due to the functions being wrapped in __nuxtTimelineWrap, which replaces the original import with a local variable declaration.

// example
const useState = __nuxtTimelineWrap("useState", _$__useState)

The keyed-functions plugin then sees a local variable instead of an import specifier and skips key injection.

🌈 Expected behavior

Wrapping should ideally happen after key injection, if possible.
