* fix: prevent creation of funnels with duplicate names
- Fixed Update method to validate duplicate names before updating
- Added proper duplicate name validation that excludes the current funnel being updated
- Fixed incorrect error wrapping in Update method that was marking all errors as "already exists"
- Fixed typo in error message ("funnelr" -> "funnel")
- Added comprehensive tests for duplicate name validation in both Create and Update operations
- Used internal errors package for consistent error handling
The funnel API now properly prevents creating or updating funnels with duplicate names
within the same organization, resolving issues where duplicate funnels could be created
but would fail during retrieval.
