Rename "Markdown Summary" field for notebooks. Add to FE on /create/notebook/ form.

[leonardthethird]

Context

It's hard to remember to use the "Markdown Summary" field (only available in django admin) when creating a notebook, resulting in awkward situations where we're displaying raw markdown on feed tiles:

Summary

Successfully renamed the "Markdown Summary" field to "Feed Tile Summary" and added it to the frontend notebook creation form at /create/notebook/.

Backend Changes:

• Renamed markdown_summary to feed_tile_summary in the Notebook model with a helpful description
• Created migration 0029_rename_markdown_summary_to_feed_tile_summary.py
• Updated NotebookSerializer, NotebookAdmin, posts/translation.py, and posts/services/versioning.py

Frontend Changes:

• Updated TypeScript type definition in types/post.ts
• Updated all components that reference this field:
  • components/post_card/notebook_tile.tsx
  • components/news_card.tsx
  • app/(main)/(home)/components/research_and_updates.tsx
• Added the field to the notebook creation form in questions/components/notebook_form.tsx with:
  • Label: "Feed Tile Summary"
  • Placeholder text explaining the field's purpose
  • Optional validation (users can leave it blank for auto-generation)
• Added translation strings to messages/en.json

The field is now more discoverable and clearly describes its purpose. When creating a notebook, users will see this optional field and can provide a custom summary for feed tiles, helping avoid the issue of raw markdown being displayed.
