Upgrade Vite to 8.0.x in publisher-command-center (#338)

* Upgrade Vite to 8.0.x in publisher-command-center

Resolves 13 Dependabot security alerts by upgrading Vite from 2.6.x to
8.0.x. Migrates esbuild JSX config to oxc equivalent for Vite 8, adds
dev server proxy for local development, and silences Bootstrap Sass
deprecation warnings per Bootstrap's official recommendation.

* Fix arrow function `this` binding in ContentsComponent

Change view from arrow function to regular function so Mithril can bind
`this` to the component state. This was a pre-existing bug masked by
Vite 2's non-strict bundling where `this` resolved to `window` instead
of `undefined`.

* Bump publisher-command-center extension version to 0.0.6

Increment version to trigger a gallery release with the Vite upgrade
and ContentsComponent bug fix.
