This PR introduces a few changes to improve turbopack compatibility and
ensure e2e tests pass with turbopack enabled
## Changes to improve turbopack compatibility
- Use correct sideEffects configuration to fix scss issues
- Import scss directly instead of duplicating our scss rules
- Fix some scss rules that are not supported by turbopack
- Bump Next.js and all other dependencies used to build payload
## Changes to get tests to pass
For an unknown reason, flaky tests flake a lot more often in turbopack.
This PR does the following to get them to pass:
- add more `wait`s
- fix actual flakes by ensuring previous operations are properly awaited
## Blocking turbopack bugs
- [X] https://github.com/vercel/next.js/issues/76464
- Fix PR: https://github.com/vercel/next.js/pull/76545
- Once fixed: change `"sideEffectsDisabled":` back to `"sideEffects":`
## Non-blocking turbopack bugs

**BREAKING CHANGE:**
This bumps the **minimum required Next.js** version from 15.0.0 to
15.2.3. This update is necessary due to a critical security
vulnerability found in earlier Next.js versions, which requires an
exception to our standard semantic versioning process.
Additionally, this bumps all templates to the latest Next.js and Payload
versions.
This bumps next.js to 15.2.0 in our monorepo, as well as all @types/react and @types/react-dom versions. Additionally, it removes the obsolete `peerDependencies` property from our root package.json.
This PR also fixes 2 bugs introduced by Next.js 15.2.0. This highlights why running our test suite against the latest Next.js, to make sure Payload is compatible, version is important.
## 1. handleWhereChange running endlessly
Upgrading to Next.js 15.2.0 caused `handleWhereChange` to be continuously called by a `useEffect` when the list view filters were opened, leading to a React error - I did not investigate why upgrading the Next.js version caused that, but this PR fixes it by making use of the more predictable `useEffectEvent`.
## 2. Custom Block and Array label React key errors
Upgrading to Next.js 15.2.0 caused react key errors when rendering custom block and array row labels on the server. This has been fixed by rendering those with a key
## 3. Table React key errors
When rendering a `Table`, a React key error is thrown since Next.js 15.2.0
