fix(ui): remove frontend debug console logs

[Ghraven]

What changed

• Removed leftover frontend console.log calls from raw material loading and template testing flows.
• Stopped passing a placeholder click handler that only logged Create sketch; the button is already wrapped by NewSketch.

Problem

A few shipped UI paths still wrote raw data or placeholder messages to the browser console. That can make local debugging noisier and may expose unnecessary API response details during normal app usage.

Before / after

Before:

• Opening raw materials logged the fetched materials object.
• Running a template test logged the full response object.
• Clicking the empty sketches action emitted a placeholder console message before the real NewSketch wrapper handled creation.

After:

• These UI paths no longer emit debug-only console output.
• Sketch creation behavior remains delegated to the existing NewSketch wrapper.

Verification

• git diff --check passes.
• corepack yarn install --frozen-lockfile completed successfully.
• corepack yarn typecheck is currently blocked by existing project-wide TypeScript errors unrelated to these files, including missing Tiptap modules and table/router typing errors.
• A targeted ESLint run is currently blocked because .eslintrc.cjs requires @typescript-eslint/parser, but that parser is not installed by the lockfile.
