launch form: rotate meta_key with the salt on 409 so an edited retry is not stuck

[kevincodex1]

A metadata key is locked to the details it was first registered with. The form kept its key for the whole session and only rotated the salt on 409, so after a failed or cancelled attempt an edit to name/image/etc. hit 409 on every retry. Now a 409 starts a fresh attempt: new key and new salt together, and the new key stays fixed through findSalt. Identical retries remain idempotent (same key, same salt, 200).

Summary by CodeRabbit

• Bug Fixes
  • Improved launch retry handling for conflicting metadata.
  • Metadata registration now preserves the correct key across retries and rotates the key and salt when conflicts require another attempt.

📝 Walkthrough

Walkthrough

Launch metadata registration now keeps the metadata key mutable during an attempt. A 409 response rotates both the metadata key and salt before retrying.

Changes

Launch metadata retry handling

Layer / File(s)	Summary
Mutable metadata retry state app/src/components/launchpad/LaunchForm.tsx	The launch attempt initializes a mutable metadata key from its persistent reference. A 409 response generates and stores a new metadata key and salt before retrying registration.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 2b060

Launch retries now refresh both metadata key and salt after a 409 conflict while preserving values for identical retries. No current merge-blocking risk is identified.
