Upgrade to operator-sdk 1.41.1

Rescaffold the watcher-operator to operator-sdk 1.41.1, which includes:
 - Reorganize project structure (pkg/ -> internal/)
 - Move webhook implementations to internal/webhook/v1beta1/
 - Add new cmd/main.go entrypoint with updated controller initialization
 - Update RBAC, certmanager, and prometheus configurations
 - Enhance network policies for metrics and webhook traffic
 - Set watcher as defaulting resource in PROJECT file
 - Remove auto-generated test suite scaffolding
 - Update build workflow and Dockerfile to version 1.41.1

This upgrade modernizes the operator structure and aligns with the latest
operator-sdk best practices.
