Using 0.0.0.0 as IP address in env.sh causes api issues

[szymon-romanko]

Describe the bug
If you use 0.0.0.0 as IP address when creating .env file with env.sh script, tracecat wont work properly
Any api calls from frontend to backend will fail, causing for example error where login form won't show up (similar to #779)

To reproduce
Follow steps from https://docs.tracecat.com/quickstart/install#docker-compose

1. Clone repo - git clone https://github.com/TracecatHQ/tracecat.git
2. Run env.sh, leave first and third option default, but in second (where you are asked to specify server ip address) set it to 0.0.0.0
3. Start app - docker compose up -d
4. Go to web ui (either localhost or local ip address) and try to log in
5. Login form won't display properly (see Login form doesn't show up #779 for screenshots)

Problem comes from frontend trying to send api requests to wrong (0.0.0.0) address

Expected behavior
This isn't really problem with the app, but it can be confusing for new users. When they are installing tracecat and want it to listen on all interfaces, its common to set ip address to 0.0.0.0
A note of this in documentation or env.sh script displaying a warning would be probably enough

@szymon-romanko thanks for looking into this. Will repro on my end and look for a fix / update docs. We definitely have users looking to modify the IP address and there should be more docs around this.

By the way, if you haven't already please join our #contributors channel in Discord! DM me and introduce yourself. Would love to support a Tracecat community member better 🦾
