fix(handlers): add $6 placeholder for 'pending' in insertMCPDelegationRow

The INSERT has 8 column names but the VALUES clause only had 5
positional placeholders ($1-$5). The 'pending' status was passed as a
raw string literal instead of a placeholder, and pq's internal arg
count then misaligned all subsequent args.

Before (broken): VALUES ($1...$5, 'pending') with 6 args → pq error
After:           VALUES ($1...$6)   with 6 args → correct

Also adds sqlmock coverage for insertMCPDelegationRow (success + DB
error) and updateMCPDelegationStatus (success + error detail + DB
error logged-not-returned), bringing both from 0% to 100% coverage.
