PR #2116 by ksylvan and dependabot: fix(web): repair the chat page and modernize the build toolchain

• Modernized the web stack by upgrading Tailwind, Skeleton, SvelteKit, Vite, and supporting dependencies.
• Replaced removed Skeleton components with compatible local implementations to restore UI functionality.
• Improved pre-stream chat error reporting to prevent duplication of streamed errors, and hardened vendor list parsing to return empty model arrays on malformed input.
• Fixed stream completion crashes, normalized displayed error messages, corrected toast stacking order, and added warning notification support.
• Restored linting, formatting, testing, and pnpm override configuration, and preserved custom themes through the Tailwind CSS-based configuration migration.
