Dependabot: switch update cadence to monthly on master

[Copilot]

Dependabot was configured for weekly checks; this updates the repo to a monthly cadence and aligns all update jobs to target master. The goal is to reduce update churn while keeping dependency automation centralized on the main branch.

• Schedule policy

  • Changed schedule.interval from weekly to monthly for all configured ecosystems.

• Branch targeting

  • Added target-branch: "master" to each update block so Dependabot update PRs are opened against master.

• Coverage

  • Applied consistently across:
    • github-actions
    • maven
    • docker
    • docker-compose

updates:
  - package-ecosystem: "maven"
    directory: "/"
    target-branch: "master"
    schedule:
      interval: "monthly"

🟢 Approval recommended

The YAML is valid and consistently applies the intended monthly cadence and master targeting across all Dependabot update blocks.
