fix(handlers): compile error in approvals.go + broken test mock in p1102

- approvals.go: err was already declared at line 37 (ctxJSON, err := json.Marshal).
  Reusing with = instead of := to fix "no new variables on left side of :=".
- approvals_test.go: TestApprovals_Create_NilContextFallsBackToEmptyJSON mock
  expected 6 args for an INSERT with 5 columns. Remove spurious
  sqlmock.AnyArg() that caused "expected 6, got 5 arguments" at runtime.
