Use shared Renovate preset and update pnpm to v10

[bdrhn9]

Migrate the repository from pnpm v9 to v10 and adopt the shared Renovate preset from api3dao/renovate-config. This improves supply chain security via minimumReleaseAge enforcement and standardizes Renovate configuration across projects.

As a part of https://github.com/api3dao/tasks/issues/1855

Changes beyond the task description

• Dependency downgrades (dotenv, immer, rimraf, @types/node, hardhat): Latest versions were published
  within the 14-day minimumReleaseAge window. Lowered each semver lower bound by one patch so pnpm can resolve a
  mature version within the range. Caret ranges still allow future updates once they age past 14 days.
• Dockerfile: Updated npm install -g pnpm@9 → pnpm@10 to match the new packageManager field.

Test plan

• Run e2e flow defined under local-test-configuration
• CI pipeline passes
