chore(web,ui): upgrade Tailwind toolchain versions

[9renpoto]

Motivation

• Bring Tailwind and its post-processing toolchain up to newer supported versions across the web and UI workspaces to stay current with Astro/Storybook integration and bugfixes.

Description

• Bumped tailwindcss to ^4.1.12, postcss to ^8.5.6, and autoprefixer to ^10.4.21 in both @vgmo/web and @vgmo/ui package.json manifests.
• Upgraded @astrojs/tailwind to ^6.0.2 in @vgmo/web package.json to align with the new Tailwind/PostCSS versions.
• Only the workspace package.json files were modified; the project lockfile was not regenerated in this environment due to restricted registry access.

Testing

• Ran npm run build --workspaces and the workspace builds completed successfully (Astro and TypeScript builds passed).
• Ran npm test --workspaces and the test run partially failed because @vgmo/ui requires Playwright browser binaries which are not installed in this environment, causing Vitest to error; other workspaces' tests executed.
• Attempted npm install -w @vgmo/web -w @vgmo/ui -D tailwindcss@latest autoprefixer@latest postcss@latest @astrojs/tailwind@latest but the registry returned 403 Forbidden, preventing dependency installation and lockfile regeneration.
