Feat: add test series field

[MarceloRobert]

Description

Adds a new field to the tests model called "series" which will be a junction of path + platform.
The approach is that we can create a "half-series" on the tests table, and then join on builds and use the similar build series field in order to identify a test. This is done specially so that we can avoid async insertion problems, when a test is inserted before its related build is inserted; it also allows us to use a generated column instead of a trigger and avoids having to query for the platform under a json field, with index.

For testing, also adds a new endpoint called "TestStatusSeries" similar to TestStatusHistory, but using the series fields.

Note

Since TestStatusSeries and TestStatusHistory use different fields for filtering, their return is different. Not only that, but there is also a difference between filtering by checkout origin vs test origin specially for tests that are related to builds related to nonexistent checkouts. Example: http://localhost:5173/test/maestro:68ba7c39b9811ea53d062635

While I was checking the migrations, I also saw that the cache tables are being created on the postgres database, so I also fixed the database router while I was at it.
Also, when comparing TestStatusSeries with TestStatusHistory, I saw that tests related to nonexistent checkouts were simply not returning any history, so I fixed that too.

Changes

• Added series field to tests model
• Added TestStatusSeries endpoint for testing
• Fixed database router by avoiding cache tables on default database
• Fixed problem where independent tests weren't returning the status history

How to test

• Run the local database
• Apply the migration (make sure they are applied in the right order)
• Check the database for the series field, and check the endpoint as well.

Closes #1167
Closes #1475

Pull Request Overview

This PR introduces a new series field to the tests model for more efficient test identification and querying. The series field is a junction of path + platform and uses MD5 hashing to create unique identifiers. This allows for better handling of async insertion problems and provides a more efficient way to query test status history using series-based identification rather than complex joins.

Key changes include:

• Added a generated series field to the Tests model with MD5 hash of path + platform
• Created a new TestStatusSeries endpoint mirroring TestStatusHistory functionality
• Fixed database router to prevent cache tables from being created on the default database

backend/kernelCI_app/views/testStatusHistoryView.py:1

• The path field is annotated as str but has a default value of None, which creates a type mismatch. It should be Optional[str] to match the nullable default value.

backend/kernelCI_app/queries/test.py:64

• Several parameters (path, git_repository_url, git_repository_branch, config_name) are typed as required str but the corresponding request model shows these can be None. The function signature should use Optional[str] to match the API contract.
