Add automatic pod restart on PTP security secret changes

Watch for changes to secrets referenced in PtpConfig and automatically restart linuxptp-daemon pods via SHA256 hash annotation. Each profile can specify independent secret and sa_file configurations. Security volumes use -ptpconfig-sec suffix for identification and are preserved during PtpOperatorConfig reconciliation via merge logic.
