Migrate swportal from Pelican to Next.js

[chestercheng]

Background

The current swportal website is built using Pelican. We propose migrating to Next.js, which we're already successfully using in other sciwork projects (e.g. swconf2024 and swconf2023).

Benefits of Migration

• Enhanced content Management: Using React components instead of writing HTML in RST/Markdown.

• Dynamic features: Better handling of dynamic content through client-side rendering for interactive features like "upcoming events.

What contents are planned to be changed from SSR to CSR?

[chestercheng]

Since our website is mainly used for displaying information, most parts will still use SSR for better SEO.
The upcoming event block will use CSR, so we won't need to constantly push updates to remove outdated content from it.

Sounds like a plan
