Due to nature of server-side rendering, navigation within the admin
panel can lead to slow page response times. This can lead to the feeling
of an unresponsive app after clicking a link, for example, where the
page remains in a stale state while the server is processing. This is
especially noticeable on slow networks when navigating to data heavy or
process intensive pages.
To alleviate the bad UX that this causes, the user needs immediate
visual indication that _something_ is taking place. This PR renders a
progress bar in the admin panel which is immediately displayed when a
user clicks a link, and incrementally grows in size until the new route
has loaded in.

To tie into the progress bar, you'll need to use Payload's new `Link`
component instead of the one provided by Next.js:
```diff
- import { Link } from 'next/link'
+ import { Link } from '@payloadcms/ui'
```
Here's an example:
```tsx
import { Link } from '@payloadcms/ui'
const MyComponent = () => {
return (
<Link href="/somewhere">
Go Somewhere
</Link>
)
}
```
In order to trigger route transitions for a direct router event such as
`router.push`, you'll need to wrap your function calls with the
`startRouteTransition` method provided by the `useRouteTransition` hook.
```ts
'use client'
import React, { useCallback } from 'react'
import { useTransition } from '@payloadcms/ui'
import { useRouter } from 'next/navigation'
const MyComponent: React.FC = () => {
const router = useRouter()
const { startRouteTransition } = useRouteTransition()
const redirectSomewhere = useCallback(() => {
startRouteTransition(() => router.push('/somewhere'))
}, [startRouteTransition, router])
// ...
}
```
In the future [Next.js might provide native support for
this](https://github.com/vercel/next.js/discussions/41934#discussioncomment-12077414),
and if it does, this implementation can likely be simplified.
Of course there are other ways of achieving this, such as with
[Suspense](https://react.dev/reference/react/Suspense), but they all
come with a different set of caveats. For example with Suspense, you
must provide a fallback component. This means that the user might be
able to immediately navigate to the new page, which is good, but they'd
be presented with a skeleton UI while the other parts of the page stream
in. Not necessarily an improvement to UX as there would be multiple
loading states with this approach.
There are other problems with using Suspense as well. Our default
template, for example, contains the app header and sidebar which are not
rendered within the root layout. This means that they need to stream in
every single time. On fast networks, this would also lead to a
noticeable "blink" unless there is some mechanism by which we can detect
and defer the fallback from ever rendering in such cases. Might still be
worth exploring in the future though.
This PR adds a button to the `/account` view which allows users to reset
their preferences on-demand. This is to that editors can quickly reset their
preferences via the admin ui without the need of accessing the db directly,
which was simply not possible before. To do this, we add a new button at
the bottom of the account view which performs a standard `DELETE`
request using the REST API to the `'payload-preferences'` collection.

Improves the admin e2e test splitting by grouping them by type with
semantic names as opposed to numerically. This will provide much needed
clarity to exactly _where_ new admin tests should be written and help to
quickly distinguish the areas of failure within the CI overview.
