Checklist before requesting a review

• I have performed a self-review of my code
• If it is a core feature, I have added thorough tests.

Testing

I've tested on a clean clone and here's how you can too:

git clone [email protected]:0-BSCode/Budgeteer.git
cd Budgeteer/
git checkout cd--docker-compose

# run all services at once
bun run all:up

Then visit localhost:5173 to test the client application.

Couple of nits and questions.

Is this needed? Don't think our other use cases are logging errors since it's handled by Hono's global error handler

[Luzefiru]

Ah whoops, this was for debugging. I'll remove it.
