docs: unify guide subsection overviews on card grids

[pratyush618]

Every /{sdk}/guides/{section} overview page now uses the same Card-grid format.

Before

Subsection index pages were a mix: most were Markdown tables (| Guide | Description |), the two workflows indexes used Card grids, and the integrations indexes were grouped bullet lists. The top-level Python guides overview was also missing a card for its Dashboard subsection.

After

• Converted all ~24 subsection index pages (core, reliability, operations, workflows, resources, observability, extensibility, integrations, advanced-execution) across Python / Node / Java to <Cards> grids — one <Card> per child page with a one-line gloss, order preserved.
• integrations pages keep their ## Observability / ## Web frameworks groupings, each with its own grid.
• Added the missing Dashboard card to the Python guides overview, and an "In this section" grid to the Python dashboard index (surfaces the previously-unlinked SSO page).
• Dropped redundant fumadocs-ui Card/Callout imports — those components are globally registered.

Verification

• pnpm build — all pages compile and prerender; spot-checked rendered HTML (e.g. /python/guides/core = 8 cards, /node/guides/integrations keeps both group headings).
• pnpm run typecheck clean.

Summary by CodeRabbit

• Documentation
  • Updated Java, Node.js, and Python guide landing pages with card-based navigation for improved browsing.
  • Preserved existing guide links and descriptions across core, extensibility, integrations, observability, operations, reliability, resources, workflows, and advanced execution sections.
  • Added a Dashboard entry to the Python guides overview.
  • Added Dashboard subsection links for Authentication, SSO, task and queue overrides, and the REST API.

📝 Walkthrough

Walkthrough

Guide navigation across Java, Node, and Python documentation is converted from Markdown tables or lists to MDX Cards and Card layouts. Python also adds Dashboard navigation, while redundant component imports are removed from selected pages.
