fix(audience-sample-app): make sample build under Unity 2022 + Unity 6 (SDK-256)

- Adds Immutable.Audience.Samples.SampleApp.Editor.asmdef pinning ScriptingBackendOverride.cs into a
  discoverable Editor assembly; without an asmdef the implicit Assembly-CSharp-Editor may not be
  picked up by Unity 6's sandboxed test-runner build context.
- Bumps com.unity.test-framework 1.1.33 -> 1.4.5 so [UnityTest] coroutines surface timeouts
  correctly under UTF 2.x.
- Drops com.unity.toolchain.macos-arm64-linux-x86_64 2.0.5; the toolchain naming convention changed
  past 2022 and Unity auto-selects the macOS toolchain anyway.
- Deletes packages-lock.json so each Unity version regenerates a lock matching its own UPM
  resolution.
- Guards FindObjectOfType<AudienceSample> with #if UNITY_2023_1_OR_NEWER so APIUpdater can't
  silently drop the includeInactive parameter when rewriting to FindFirstObjectByType.
- Converts deadline-style WaitForSecondsRealtime in two test methods to a polling pattern
  (Time.realtimeSinceStartup against a budget); adds the WaitForCondition helper used elsewhere in
  the test suite.
