docs: Docs updates (#3459)

* docs(cli): document device-code login and config reset guidance; renumber sections

* docs(cli): fix duplicate numbering (renumber Login/API Keys/Configuration sections)

* docs: Fix webhook documentation to include meta dict in all webhook payloads

- Add note explaining that meta objects from kickoff requests are included in all webhook payloads
- Update webhook examples to show proper payload structure including meta field
- Fix webhook examples to match actual API implementation
- Apply changes to English, Korean, and Portuguese documentation

Resolves the documentation gap where meta dict passing to webhooks was not documented despite being implemented in the API.

* WIP: CrewAI docs theme, changelog, GEO, localization

* docs(cli): fix merge markers; ensure mode: "wide"; convert ASCII tables to Markdown (en/pt-BR/ko)

* docs: add group icons across locales; split Automation/Integrations; update tools overviews and links
