Updates the minimal supported versions of next.js to
[`15.0.0-canary.173`](https://github.com/vercel/next.js/releases/tag/v15.0.0-canary.173)
and react to `19.0.0-rc-3edc000d-20240926`.

Adds neccessary awaits according to this breaking change
https://github.com/vercel/next.js/pull/68812

## Breaking Changes

The `params` and `searchParams` types in
`app/(payload)/admin/[[...segments]]/page.tsx` and
`app/(payload)/admin/[[...segments]]/not-found.tsx` must be changed to
promises:

```diff
- type Args = {
-   params: {
-     segments: string[]
-   }
-   searchParams: {
-     [key: string]: string | string[]
-   }
- }

+ type Args = {
+   params: Promise<{
+     segments: string[]
+   }>
+   searchParams: Promise<{
+     [key: string]: string | string[]
+   }>
+ }

```
