fix(server): load integration jest config transpile-only; drop tsx pin (#21563)

## Context

Follow-up to [#21559](https://github.com/twentyhq/twenty/pull/21559)
(the esbuild 0.28.1 security bump). That PR had to pin `tsx` to `4.21.0`
to avoid a CI-only `server-integration-test` failure. This removes the
need for that pin by fixing the root cause.

## Root cause

The integration-test command boots jest with `NODE_OPTIONS="--import
tsx/esm"`, while jest *also* compiles `jest-integration.config.ts` with
**ts-node, type-checking on**. Two TypeScript transformers run over the
same file:

- tsx's loader transpiles `node-environment.interface.ts` via esbuild,
downleveling the enum to `var NodeEnvironment = (…)(NodeEnvironment ||
{})`.
- jest's ts-node then *type-checks that downleveled output* and rejects
it with `TS7022: 'NodeEnvironment' … referenced directly or indirectly
in its own initializer`.

It's not a real type error and not esbuild's fault — esbuild's output is
valid JS, just not valid TS to re-type-check. It only surfaced once
`tsx` resolved to `4.22.x` (whose loader feeds that output into
ts-node), which is why #21559 pinned tsx to 4.21.0.

Verified in isolation: ts-node type-checking esbuild's downleveled enum
→ `TS7022`; the same under `transpileOnly`/`TS_NODE_TRANSPILE_ONLY=true`
→ clean.

## Fix

Run the integration jest config **transpile-only**
(`TS_NODE_TRANSPILE_ONLY=true` on the `test:integration` target, base +
`with-db-reset`). The config file doesn't need type-checking at boot,
and jest's ts-node now emits JS without re-type-checking esbuild's
output — eliminating the whole class of tsx/esbuild-downleveling
sensitivity.

With the collision gone, drop the workaround from the root
`package.json`:
- removed the `tsx: 4.21.0` resolution
- removed the `tsx/esbuild: 0.28.1` resolution

`tsx`'s `^4.x` ranges now resolve to **4.22.4**, which pins esbuild
`~0.28.0` → **0.28.1** on its own, so esbuild stays 0.28.1 across the
lockfile with no resolution. The `//resolutions` doc block is updated
accordingly.

## Verification

- `yarn install` clean; lockfile has only esbuild 0.28.1; tsx resolves
to 4.22.4.
- `jest --config ./jest-integration.config.ts --listTests` with tsx
4.22.4 + `TS_NODE_TRANSPILE_ONLY=true` loads the config and lists all
420 suites.
- CI `server-integration-test` is the real validator (the failure was
CI-only).
