ux: Clean up interface and improve user flow

UX Improvements:
- Remove rocket emojis from buttons and labels
- Remove '(NEW - No Race Condition)' text from step labels
- Remove recommended text about race condition elimination
- Remove legacy Step 5 conversion button entirely
- Fix step numbering: Convert is Step 3, Password/Cert are Steps 4-5, Review is Step 6
- Streamlined flow: Step 3 (Convert) only appears after Step 2 (Upload) completion
- Single, clean conversion path without legacy options

Result: Cleaner, more professional interface with simplified user flow.
