azure-mgmt-agrifood needs typing updates for mypy version 2.1.0

**ACTION NEEDED:** This version of mypy will be merged on **2026-10-12**. The build will begin to fail for this library if errors are not fixed.

**Library name:** azure-mgmt-agrifood
**Mypy version:** 2.1.0
**Mypy Build:** [Link to build (2026-08-11)](https://dev.azure.com/azure-sdk/internal/_build/results?buildId=6683421&view=logs&j=1c9d2a78-6cd4-570f-8bfd-7e176dcfa70f&t=c4b2a078-69a7-55a2-d776-67715c71590f)
**How to fix:** Run the `next-mypy` azpysdk command at the library package-level and resolve the typing errors.
1) `/mnt/vss/_work/1/s>pip install -e ./eng/tools/azure-sdk-tools`
2) `../azure-mgmt-agrifood>azpysdk next-mypy --isolate .`

See the [Typing Guide](https://github.com/Azure/azure-sdk-for-python/blob/main/doc/dev/static_type_checking.md#run-mypy) for more information.

Install the local azure-sdk-tools package, then run `azpysdk next-mypy --isolate .` from the azure-mgmt-agrifood package as described in the issue. Read the Typing Guide for context and resolve the reported typing errors; done means the package passes the upcoming mypy 2.1.0 build.
