feat: Migrate from `prettier`/`eslint` to `biome`

[Repiteo]

Converts the existing linter/formatter to the new kid on the block: biome. Replaces prettier & eslint entirely by doing the same thing but at a significantly expedited rate. All the relevant settings were migrated over with little effort, and only a handful of manual adjustments needed to be made after its initial check (making some enums pascal-case); otherwise, everything was automatically taken care of in less than a second!
