Results Page: Filter Results tests by Confidence - High Confidence first by default

[Carla-Moz]

Update: the issue was mentioning sorting, where we wanted to filter the results by default. Sorting is too difficult with our data structure as a first outreachy issue. The issue description has been updated to reflect that. Thanks

Description:
As a user, I want the results view to be filtered by confidence level, with high-confidence results displayed first by default.

Steps to Reproduce:

1. Read the PerfCompare Documentation to get familiar with the app.
2. Navigate to the results table: Results
3. Observe that the column filters are not filtered by confidence level, with high-confidence results displayed first by default

Acceptance Criteria:

1. Results should be filtered by confidence with high confidence first by default.
