Add a launch penalty configuration input on the creator dashboard settings tab

[Chucks1093]

Summary

Creators can set a custom launch penalty fee for early sellers but there is no UI for this. A launch penalty input on the creator dashboard settings tab should let creators set the penalty percentage between 0% and 20% and submit the set_launch_penalty contract call.

Scope

• Add a Launch Penalty section to the creator dashboard settings tab
• Show the current penalty percentage fetched from the key detail API (launchPenaltyBps)
• Render a percentage input (0–20%) pre-filled with the current value
• Show helper text: 'Applied to sells within the first 7 days after key creation'
• Submit via the set_launch_penalty contract function and show a success toast on confirmation

Acceptance Criteria

• Current penalty value pre-filled on mount
• Input constrained to 0–20%
• Helper text shown below the input
• Success toast shown after contract confirmation
• Updated penalty reflected in the input without a page reload

ETA: 12 hours
