APIRecorder uses deprecated record.EventRecorder and drops filterFns

## Problem

1. `NewAPIRecorder` accepts `record.EventRecorder` which is deprecated in favor of `events.EventRecorder` (`events.k8s.io/v1` API)
2. `WithAnnotations` silently drops `filterFns` on every call due to not forwarding them to `NewAPIRecorder`
3. `FilterFn` godoc incorrectly states return false prevents recording (should be return true)
4. `Eventf` call passes empty action string, which can cause `events.k8s.io/v1` rejection

Start by locating NewAPIRecorder, WithAnnotations, FilterFn, and Eventf in the recorder package. Review related PR #1052 and any nearby tests or call sites to understand the current behavior. Done means the four listed API, filter forwarding, documentation, and action-string problems are corrected without dropping existing behavior.
