[BUG] Cannot Connect to AWS DocumentDB (MongoDB)

## Description
I cannot login to AWS DocumentDB, as the URI string contains symbols and escaping them does not work.

It also forces me to specify a database, when MongoDB can have many databases in the same way PostgreSQL and Oracle DB have schemas.

## Steps to Reproduce
Try to add a MongoDB connection to AWS DocumentDB

## Expected Behavior
Make the database field optional, and list the databases on the left hand side.

## Actual Behavior
I cannot connect due to these inconveniences.

## Environment
Please provide the following information:

- **LibreDB Studio Version**: 0.15.0
- **Browser**: Chrome
- **OS**: macOS
- **Node.js/Bun Version**: Why are you asking me? This is your Docker image.
- **Database Type**: AWS DocumentDB
- **Database Version**: Unknown

## Possible Solution
Actually test your DB drivers with AWS DocumentDB and MongoDB in general...

Start by reproducing an AWS DocumentDB connection with symbols in the URI and without a database name, then trace the MongoDB connection flow. Done means credentials and escaped URI symbols work, the database field is optional, and available databases appear on the left.
