SG-38306 Python2 Removal - Part 8 - Remove deprecated ensure_ascii parameter from SG object

[julien-lang]

The ensure_ascii parameter was added in the Python 2 world when strings and bytes could be confusing when loading/dumping JSON.

Now, in the Python 3 world, this complexity does not exist anymore as there is clear different between the 2 types. Json dump will always return a string. And loader will convert any "json string" type to a default Python string (i.e. a unicode type in Py2).

Pull Request Overview

This PR removes the legacy ensure_ascii parameter from the Shotgun client and its mock, cleans up related JSON decoding code, and updates tests to reflect the new default JSON encoding behavior.

• Drop ensure_ascii argument and methods in Shotgun and Mockgun
• Remove old tests and helper for Python 2 ensure_ascii behavior; add a new test verifying non-ASCII payload encoding
• Update client and API code to always use json.dumps(..., ensure_ascii=False)

• [nitpick] The ensure_ascii parameter is no longer used inside this helper; consider removing it from the signature to avoid unused parameters.

• [nitpick] The docstring is inaccurate and has a grammar typo (SG'payload). Please reword to clearly state that the JSON payload is dumped with ensure_ascii=False to allow non-ASCII characters.

 """Make sure SG'payload is using ensure_ascii for json dumps"""
