chore(ci|cli): improve coverage ci and compare fixtures python script

[spencer-tb]

🗒️ Description

Pre-dominantly updates the compare fixtures python script we use within the coverage ci:

• Before to remove >3000 duplicates the script would take many minutes. Now its near instant.
• A bug is additionally resolved where all duplicates were not removed on the first pass, before it would take 3 runs to remove all duplicates (in my case testing locally). Now all duplicates are removed on the first pass.

Improved logging is added to the now "Print Unique Test IDs that will be covered" CI coverage step. This will print the test IDs of all the tests that will run for both BASE (main) and PATCH (the branch you have updated). These IDs are resolved from the compare_fixtures.py script. This will help to see if anything obvious is removed within your PR.

Prague is added back for coverage checks!
