core/tracker: trim state committees (#3868)

KaloyanTanev · web-flow · commit c3d71694175b · 2025-08-04T11:42:30.000Z
Under specific circumstances of attestation tracking feature flag being enabled AND block not being processed correctly (could be of multiple reasons), state committees were not cleaned up.

Include trimming of state committees alongside with submissions.
