Summary: Embedder adds schematic upload feature

Why It Matters: This change lets users upload schematic files directly. This could make it easier for engineers to use the tool with their hardware designs.

What Changed:

• The instruction "npm install -g @embedder/embedder" was replaced with a file upload option.
• The new text says "Drop to upload your schematic here file may not exceed 50 MB Or click the field above to browse".
• The installation command "npm install -g @embedder/embedder" was moved from the top section to the bottom "Ready to get started?" section.
