[BUG][P0] Duplicate variable declarations in API routes

[l0gic]

Describe the bug

Duplicate variable declarations exist in API route files, causing build errors.

Affected Files

1. src/app/api/leads/[id]/convert/route.ts:171

The POST function name is defined multiple times.

2. src/app/api/rum/session/route.ts:78

The session variable is declared multiple times.

Expected behavior

Each variable/function should be declared only once in its scope.

Possible Solution

Rename or remove duplicate declarations. For the POST function issue, ensure there's only one export per route handler.
