Oleg Isonen 1b48716ff4 docs: Document MDX-backed Content Blocks (#6273)
## Summary

- Document how people create, connect, edit, validate, and publish
MDX-backed Content Blocks.
- Document the complete MCP workflow, including scoped expression
sources, frontmatter updates, diagnostics, conflicts, and disconnect
behavior.
- Add two focused screenshots for the human workflow.
- Fix issues found by a low-reasoning MCP agent while executing every
documented workflow.

Ref #6182

## Implementation notes

- Connection confirmation uses the public `confirmReplacement` field
because `confirm` is reserved as a hidden transport field.
- MCP edits frontmatter with `update-content-block-frontmatter`;
materialized MDX elements are not persistent targets for generic
instance mutation tools.
- Reload now intentionally discards a conflicted local source and
accepts the Asset's latest storage revision before an edit is reapplied.
- Generated MCP documentation and runtime contracts are updated from
their source files.

## Checklist

- [x] Document the human MDX Content Block workflow.
- [x] Document MCP discovery, connection, editing, diagnostics,
frontmatter, dynamic sources, conflicts, and disconnection.
- [x] Add only screenshots that clarify otherwise hard-to-describe UI
steps.
- [x] Test every documented MDX capability through the local MCP CLI
with a low-reasoning agent.
- [x] Reproduce and fix the replacement-confirmation schema mismatch.
- [x] Reproduce and fix persistent-session conflict reload and reapply.
- [x] Add regression tests that failed before each product fix and pass
afterward.
- [x] Regenerate runtime contracts and generated MCP documentation.
- [x] Review authoritative `docs/` content and update affected pages.
- [x] Run affected tests, typechecks, formatting, and diff checks.
