perf: drop unused MDXEditor from OSTable (cuts ~3.2 MiB eager)

[pauldambra]

Changes

The single biggest eager-bundle win in the ratchet — and it's pure dead-code removal.

OSTable defined an Editor component wrapping @mdxeditor/editor's MDXEditor, but it was never rendered (dead since a dependency version bump ~9 months ago). The unused import { linkPlugin, MDXEditor } from '@mdxeditor/editor' dragged the entire markdown-editor stack — @mdxeditor/editor + @codemirror/*, @codesandbox/sandpack-react, acorn, downshift, react-hook-form, js-yaml — into the always-loaded bundle on every page.

OSTable is the only eager importer of @mdxeditor/editor (other references are type-only JsxComponentDescriptor imports or non-eager page components), so deleting the dead Editor component (and the now-unused navigate import) removes ~3.2 MiB / ~218 modules from the app eager closure with no behaviour change — nothing rendered it.

No preview verification needed: the removed component was never on screen. The other @mdxeditor consumers (the real MDXEditor wrapper, home-page components) are unaffected and keep it in their own page chunks.

Expected impact

@mdxeditor/editor and its editor dependency tree drop out of the eager graph (~3.2 MiB, the largest single split so far). Stacked on the jspdf PR.

Eager-graph budgets are report-only until a baseline is established. Sizes are gzip of public/**/*.js; eager size is webpack module source bytes for the modules actually shipped in the entrypoint's initial chunks (post-tree-shake).
