Update Maintainers team casing, Python 3.14.5, and docs

[ydesgagn]

Summary

Routine maintenance touching team handle casing in CODEOWNERS, a Python version bump, markdownlint ignore for the generated code-review document, and architecture documentation refinements reflecting the recent bot PAT and code-owner review work.

Key changes:

• Update .github/CODEOWNERS to use the canonical @Cloud-Officer/Maintainers capitalization across all entries
• Bump Python to 3.14.5 in config/languages.yaml
• Add docs/code-review.md to markdownlint ignore globs in both .markdownlint-cli2.yaml and config/linters/.markdownlint-cli2.yaml
• Document GH_BOT_PAT usage for auto-merge approvals and require_code_owner_reviews enforcement in docs/architecture.md, including the authentication and authorization sections

Types of changes

• Bugfix (fixes an issue)
• New feature (adds functionality)
• Refactoring (improves code without changing functionality)
• Breaking change (incompatible changes)
• Build or security update (updates dependencies, libraries, or security patches)
• Code style or documentation update (formatting, renaming, or documentation changes)
• Other (please describe):

Checklist

• Unit tests added to validate my fix/feature
• I have manually tested my change
• I did not add automation test. Why ?: Configuration metadata, CODEOWNERS casing, and documentation changes only — no executable code paths to cover
• Database changes requiring migration with downtime or reprocessing of existing data
• The SOUP file lists the risk Level, requirements and verification reasoning associated with each library
• readme.md includes sections on introduction, installation, usage, and contributing
• docs/architecture.md includes sections on the architecture diagram, software units, software of unknown provenance, critical algorithms and risk controls related to PII and security
• Impact on PII, privacy regulations (CCPA/GDPR/PIPEDA), CIS benchmarks or security (availability/confidentiality/integrity); management must be notified
