fix: Remove schedule triggers from all workflows

- Remove cron schedules from blockchain-sync-verification.yml (every 6 hours)
- Remove cron schedule from node-failover-simulation.yml (daily at 2 AM)
- Remove cron schedule from p2p-network-verification.yml (every 4 hours)
- Remove cron schedule from security-scanning.yml (weekly on Monday)
- Remove cron schedule from contract-benchmarks.yml (weekly on Sunday)
- All workflows now only trigger on push or manual workflow_dispatch
