[REF-2956] New Auto Port Select Feature is Overriding Config

[deanchanter]

Describe the bug
The new auto port select feature is overriding the config. When a backend port is in config the app gets confused and loses connectivity.

To Reproduce
Steps to reproduce the behavior:
`config = ReflexappConfig(
frontend_port=3001,
backend_port=2000,
app_name="app",
api_url="http://localhost:2000",

)`

Expected behavior
If ports are in the config fall back to old method of asking the user what to do

Screenshots
If applicable, add screenshots to help explain your problem.

Specifics (please complete the following information):

• Python Version:3.11
• Reflex Version:5.1
• OS: MacOS
• Browser (Optional):FireFox

Additional context

It fails most often after a hot reload.

Thanks for reporting, we'll look into it.

Is your ideal behavior prompting the user whether to kill or change port? Or if the backend_port is provided in the config and not available, should reflex fail to start?

[deanchanter]

Yes

I guess that was kind of an xor question... if the port is defined, is your preference that reflex a) prompts xor b) fails?

[deanchanter]

Either is fine with me as long as the other is notified
