[Chore]: Clarity Bugs

Chore - Clarity Bugs

1. Description

@friedger was kind enough to point out two existing bugs in the Clarity contracts:

• An extra response wrapper in the 'complete-deposit-wrapper' function
• A recalculated value that's already saved as a variable

2. Why It's Necessary

The first issue could (possibly?) lead to an exploit since it's possible the contract call fails since the sbtc-registry contracts updates with 'map-insert'.

The second issue is strictly optimization.

3. Execution Checklist

• Remove the (ok ...) wrapper from the 'complete-deposit' contract-call
• Reuse 'version-int' variable
