Add header search paths to BranchSDKTests target

Add HEADER_SEARCH_PATHS to Debug and Release configurations for
BranchSDKTests to allow importing private SDK headers:
- $(SRCROOT)/Sources/BranchSDK
- $(SRCROOT)/Sources/BranchSDK/Private
- $(SRCROOT)/Sources/BranchSDK/Public

Also includes the deployment target fix (18.5 -> 12.0) from previous
session to allow running on iOS 18.4 simulators.
