docs(plugins): add Autodiscover plugin page in English and Spanish

[rafaelameijeiras]

Summary

Adds a new Autodiscover plugin page in English and Spanish, documenting the agent plugin that
turns endpoint system services into Pandora FMS modules: modes (--default / --list), flag
combination rules, matching rules, generated modules, diagnostics, execution limits and the
command-line reference.

Type of change

• New page
• New section / subcategory
• Edit to an existing page
• Image(s) only
• Repository/tooling change (workflows, config, template, ...)

Details

• Section affected: Plugins
• Languages:
  • English (docs/en/)
  • Spanish (docs/es/)
• Sidebar impact: none — new page inside the existing Plugins section; nav is generated
  automatically by mkdocs-awesome-pages-plugin (no mkdocs.yml or hooks.py pin change needed).
• Files changed:
  • docs/en/plugins/autodiscover.md — new English page (309 lines)
  • docs/es/plugins/autodiscover.md — new Spanish page (322 lines), content parity with English

Verification

• Validator tests pass: python3 -m unittest discover -s tests -p 'test_validate_docs.py' (10 tests, OK)
• Blocking quality gates pass: python3 scripts/validate_docs.py --fail-on blocking (summary blocking=0; 63 report-only findings are pre-existing debt in unrelated files)
• Strict build completed successfully (check one command):
  • .venv/bin/mkdocs build --strict
  • UID=$(id -u) GID=$(id -g) docker compose run --rm docs build --strict
• Images referenced with correct relative path and per-language fallback — no images are referenced by this page
• Optional: preview checked at http://localhost:8000 (preview is not validation)
