COPS-298: populate docs into backstage

[agaetep]

This pull request migrates the project documentation from a single README.md file in the repository root to a new documentation structure compatible with MkDocs and TechDocs. The documentation content remains unchanged but is now located in docs/index.md, and a mkdocs.yaml configuration file has been added to support the new documentation system.

Documentation migration and structure:

• Moved the entire documentation content from README.md to docs/index.md, ensuring no loss of information and preparing the project for MkDocs-based documentation. (README.md, docs/index.md) [1] [2]
• Added a mkdocs.yaml configuration file to enable TechDocs and define site metadata and navigation. (mkdocs.yaml)

Repository organization:

• The root README.md file has been removed and replaced with a reference to the new documentation entry point. (README.md)

Walkthrough

Adds documentation only: a MkDocs configuration (mkdocs.yaml), a comprehensive documentation page (docs/index.md) (badges, features, architecture/sequence diagrams, quick start, config, Docker/Helm deployment, health endpoints, license), and a README update referencing docs/. No code or runtime logic changed.

Changes

Cohort / File(s)	Summary
Documentation Configuration mkdocs.yaml	Added MkDocs site configuration (site_name, site_description, nav pointing to index.md, and techdocs-core plugin).
Documentation Content docs/index.md	Added full project documentation: branding/badges, features, architecture (Mermaid diagrams), access-check sequence diagram, quick start (prereqs, local dev, API generation, build, tests, run), environment variable/config table, Docker example commands, health endpoints, Kubernetes/Helm guidance, project structure, and license.
Repository README README.md	Updated README to reference the new docs/ directory and adjusted the project-structure code fence language to plain text.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10–15 minutes

• Verify shell commands and example values in docs/index.md.
• Confirm environment variable names/defaults and health endpoint descriptions match actual code/config.
• Check mkdocs.yaml nav path and plugin configuration for correct rendering.

7-7: Fix grammar: use "An" before vowel sounds.

This issue was already flagged in previous reviews. The sentence should read "An access check service" rather than "A access check service".

-A access check service for the LFX v2 platform, providing centralized authorization and permission management across LFX services.

171-188: Add language specifier to fenced code block.

This issue was already flagged in previous reviews. Markdown linting tools (including markdownlint) require fenced code blocks to specify a language. Since this is a directory structure listing, use ```text as the opening fence.

1-204: Documentation structure and content look good overall.

The documentation is comprehensive and well-organized, covering architecture, quick start, configuration, deployment options (Docker and Kubernetes/Helm), and operational endpoints. The Mermaid diagrams effectively illustrate the platform flow and access check sequence. Consider requesting verification that all linked resources (e.g., GitHub repository, LICENSE file) are accessible and that the mkdocs.yaml and supporting configuration work as intended.
