* feat(labrinth): rework v3 side types to a single `environment` field
This field is meant to be able to represent the existing v2 side type
information and beyond, in a way that may also be slightly easier to
comprehend.
* chore(labrinth/migrations): use proper val for `HAVING` clause
* feat(labrinth): add `side_types_migration_review_status` field to projects
* chore(clippy): enable and fix many stricter lints
These ensure that the codebase uses more idiomatic, performant, and
concise language constructions.
* chore: make non-Clippy compiler warnings also deny by default
* Put all ID types in the labrinth::models::ids, and reduce code duplication with them
* Rewrite labrinth::database::models::ids and rename most DB interface ID structs to be prefixed with DB
* Run sqlx prepare
