Disable automated triggers for Dependabot batch and daily status agentic workflows

[Copilot]

This change disables the two noisy/undesired agentic workflows by removing their automatic execution paths. Both workflows remain available for manual runs via workflow_dispatch.

• Scope

  • .github/workflows/dependabot-batch-prs.lock.yml
  • .github/workflows/daily-repo-status.lock.yml

• Trigger changes

  • Dependabot batch workflow
    • Removed pull_request_target trigger.
    • Removed scheduled cron trigger.
    • Kept manual dispatch trigger.
  • Daily repo status workflow
    • Removed scheduled cron trigger.
    • Kept manual dispatch trigger.

• Resulting behavior

  • No automatic runs from PR events or schedules for these workflows.
  • Maintainers can still invoke either workflow on demand from Actions UI/CLI.
