chore: Conservative dependency updates for Jinja2 security fix (#14792)

* chore: Conservative dependency updates for security

- Update Ansible from 9.1.0 to 9.2.0 (one minor version bump only)
- Update Jinja2 to ~3.1.6 to fix CVE-2025-27516 (critical security fix)
- Pin netaddr to 1.3.0 (current stable version)

This is a minimal, conservative update focused on:
1. Critical security fix for Jinja2
2. Minor ansible update for bug fixes
3. Pinning netaddr to prevent surprises

No changes to Ansible collections - keeping them unpinned for now.

* fix: Address linter issues (ruff, yamllint, shellcheck)

- Fixed ruff configuration by moving linter settings to [tool.ruff.lint] section
- Fixed ruff code issues:
  - Moved imports to top of files (E402)
  - Removed unused variables or commented them out
  - Updated string formatting from % to .format()
  - Replaced dict() calls with literals
  - Fixed assert False usage in tests
- Fixed yamllint issues:
  - Added missing newlines at end of files
  - Removed trailing spaces
  - Added document start markers (---) to YAML files
  - Fixed 'on:' truthy warnings in GitHub workflows
- Fixed shellcheck issues:
  - Properly quoted variables in shell scripts
  - Fixed A && B || C pattern with proper if/then/else
  - Improved FreeBSD rc script quoting

All linters now pass without errors related to our code changes.

* fix: Additional yamllint fixes for GitHub workflows

- Added document start markers (---) to test-effectiveness.yml
- Fixed 'on:' truthy warning by quoting as 'on:'
- Removed trailing spaces from main.yml
- Added missing newline at end of test-effectiveness.yml
