Cardano Updates

The Starlight docs build (txpipe/docs) failed compiling the v2 docset merged
in #950:

- advanced/stateful_cursor.mdx: a `</TabItem>` indented two spaces directly
  after a Markdown list was absorbed as a loose list-item paragraph, so MDX
  never saw the closing tag ("Expected the closing tag </TabItem>"). Moving the
  Tabs/TabItem JSX tags to column 0 with blank lines around the content puts
  the tags outside the list.
- how_it_works.mdx: harden the Mermaid block to canonical syntax (spaced
  dotted-link labels, non-reserved node id) so rehype-mermaid's img-svg
  renderer accepts it.

Verified with a full local `astro build` of txpipe/docs against this content:
195 pages built, the diagram rasterizes to SVG, all three new pages render.

Replace the function-level unused_variables allow with a scoped use.

* mithril-common from `0.7.5` to `0.7.6`
* mithril-stm from `0.10.35` to `0.10.36`

Bring the whole v2 docset up to a consistent, friendly-but-efficient voice and
make it easier to navigate, without breaking any existing URLs.

Highlights:
- Consistent skeleton across every source/sink/filter page (what it is + when to
  use it; consistent required/optional field markup; gotchas as asides).
- New section landing pages (sources/sinks/filters/advanced) with "which one
  should I use?" comparison tables.
- Sinks clustered by category via sidebar.order (Console -> Files -> Messaging
  -> Cloud -> Database), no file moves.
- Deduplicated the AWS/GCP credential chains onto the Sinks overview page.
- Split the 634-line Data Dictionary: concept model stays, Legacy-V1 event
  catalog moves to its own reference page.
- Components the site barely used: Tabs (install/k8s/cursor), Steps (daemon,
  kafka guide), asides for feature gating and gotchas, code-block titles.
- New pages: How it works (pipeline model + first Mermaid diagram + rollback
  handling), Quick Start (watch -> minimal daemon.toml), Troubleshooting.
- Accuracy: corrected stale "requires feature X" notes left wrong by the
  batteries-included change (only kafka/zeromq/mithril/wasm need a custom build).

Since `Cardano.Ledger.Shelley.API` will be removed, we would like to
keep re-exporting the deprecated names which will force us to change the
