chore: replace eslint/dprint with biome

[steabert]

Removes eslint and adds biome, which is a much faster linter
that can handle TypeScript out of the box, and also does formatting.

NOTE:

• dprint is gone (as biome does formatting by itself, and it covers our source code)
• biome-ignore was added where it gave an error (mostly exhaustive dependencies) as I did not want to change any logic in this PR, but I've marked them with FIXME (they either need a proper reason, or a fix)
• there is a single config file which tried to match the original format as close as possible, and I've only added the lint rules that actually affect correctness (no opinionated shenanigans about code style) with some exceptions that we also use to avoid too many inline ignores
• there was a problem with circular dependencies connected to the route map, this caused issues with HMR depending on the order of imports. The circular dependencies are now removed but it might be good in the future to add a check for this.

WANTED:

• some more testing using VS Code (It worked on my machine but I rarely use it so it's good if someone else can try it out that hasn't used biome before)

Unknown if this is a me or you issue. 😃

Format command works well for me. Also the dev enviroment still runs. So besides the issue above, LGTM.
