Simplify web interface to execute-only, improve desktop editor UX

## Web Interface
- Remove Add/Edit functionality from web interface (execute-only now)
- Remove modal dialog and command builder
- Simplified JS from 480 to 267 lines
- Users can still create/edit macros in the desktop app

## Desktop Editor
- Fix Edit button padding (set fixed width of 50px)
- Capitalize key options for better readability (Enter, Tab, etc.)
- Display keys capitalized in command list
