Replace raw SQL with Drizzle

I think the translation from SQL to drizzle for all the CRUD stuff (connections, integrations, clusters, etc.) is pretty straightforward and I like how the results look.

I'm unsure about the troubleshooting queries (the ones against targetdb), I kind of like having the raw SQL there so we can try them easier by copy&pasting.

I think the PR doesn't contain yet the migrations folder, right? I'm curious how that will look like.

@tsg Type safety uncovered that you were mixing serial/number and string for id and we have /foo/add as in /foo/<id>. What would be your choice for the final schema (in a multi tenancy database) uuids, serials?

[tsg]

@SferaDev Ah, hmm, I guess it's either:

• some string id, like UUIDv7
• or a composite PK (tenant_id + serial)

Do you have a preference?

[SferaDev]

I have a preference for uuids yeah but don't really mind if we go other way
