Feature work: More integration tests

[tippmar-nr]

• Refactor and improve azure function integration tests
• Add test for net6.0 in addition to existing net8.0 test
• Add test to verify behavior when azure function mode is not enabled

Still pending:

• Tests for an additional trigger type - will come in a separate PR or be deferred until Milestone 2
• Tests for Linux azure functions (will be deferred to Milestone 2)
