build queue: refactor & cache priority-finding for new releases

[syphar]

prep-work for the SQS ingestion from crates.io so we support a higher load in event ingestion without all these queries.

• unifies the priority logic in one struct that is easily testable.
• We still need a call (reevaluate_priorities) every now and then, which would update priorities of already queued releases, if the underlying data changes (patterns, workspace sizes, ...), but that's more optional.
• While I was on it, I also added a builder to the FakeGithubStats struct and improved some code quality in tests.
• There's a pending refactor / some duplications with test-environments, but I want to postpone that change.
• I want to directly store regex in the pattern-based priorities later, but for now I want this PR to be easily revertible.

Can you not include sqlx file changes in your PR please? The server regenerate them, and it would make the review much simpler for me without having all these file files to ignore. :')

this will only work after merge, so CI on the PR will always be red? or am I missing something?

[syphar]

but a valid point, let me think about a good solution. I could imagine one when we have the new infra, not sure with the current infra.

Isn't the CI regenerate them? Because I don't commit my sqlx changes anymore as they never work for some reason. ^^'

not on PRs, as it looks like: #3443

#3442 might help a little

[GuillaumeGomez]

Hum, maybe we should do that. Would simplify things a lot.

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

@GuillaumeGomez I rebased on main, and regenerated the sqlx files.

Looks good to me!
