## Summary
This PR fixes failing Saved-Search E2E tests by
1. Fixing a bug that caused the saved search's source to sometime not populate when navigating directly to the saved search
2. Updating the saved search modal to wait until the create saved search mutation completes and invalidates saved searches before attempting to navigate (also, added a loading state and error notifications to the modal)
3. Updated a few test assertions to be more explicit about waiting for the saved search to load

TLDR: This PR changes playwright full-stack tests to run against a local clickhouse instance (with seeded data) instead of relying on the clickhouse demo server, which can be unpredictable at times. This workflow allows us to fully control the data to make tests more predictable.
This PR:
* Adds local CH instance to the e2e dockerfile
* Adds a schema creation script
* Adds a data seeding script
* Updates playwright config
* Updates various tests to change hardcoded fields, metrics, or areas relying on play demo data
* Updates github workflow to use the dockerfile instead of separate services
* Runs against a local clickhouse instead of the demo server
Fixes: HDX-3193
Fixes: HDX-3075
* Refactors to using Page model
* Extracts common interactions into components
* Re-writes tests to conform to new model
* Adds eslint plugin for playwright best practices
* Fixes bad lints
Note: The best practice is to not use `.waitForLoadState('networkidle')` however there are several instances where components are re-rendered completely due to underlying db queries. This causes flakiness in the tests. We will re-evaluate the best solution for this in a future ticket and remove the `networkidle` from the eslint ignore list.
