Improve Web development sample with an SPA [TWP60]

[reingart]

The idea will be rewrite the lesson as a Single-Page-Application, so it can avoid to install a server (web2py, django or flask)
The original lecture has a very simple visitor count using the session

IMPORTANT: a more elaborate example will be great!

TIPs:

• Write the UI directly as HTML5 activity (editable blocks)
• Use local storage for persistence
• Use brython to code implement events (editable blocks)

Please add E2E Playwright tests
