App JSX home page

This issue should be resolved by:

User Input
1) Password Length
2) Checkbox [uppercase, lowercase,....]

Action
1) Generate Password
2) Copy Password

No file or test is named. Start by locating the app's home-page JSX and reviewing the existing UI entry point; implement the listed password-length and character-option inputs plus Generate Password and Copy Password actions. Done means the page supports those inputs and both actions work as requested.
