evaluateFinishedRecording throws TypeError when called with null

[hsusul]

Describe the bug

In src/helpers/recordingValidation.js:

evaluateFinishedRecording({ blobSize, receivedAudioData } = {}) defaults its parameter using = {}, which only triggers when the argument is undefined. When called with null or a non-object primitive, it throws:

TypeError: Cannot destructure property 'blobSize' of 'null' as it is null.

To Reproduce

1. Call evaluateFinishedRecording(null) -> throws TypeError.

Expected Behavior

evaluateFinishedRecording should safely handle null and non-object inputs, returning { usable: false, reason: "no-audio-data" } without throwing an error.

Closing together with #1840 — full reasoning over there. Thanks for the report, @hsusul!
