dx serve output is not entirely clear

[foresterre]

Problem

Running dx serve after initiating a new app logs a panic during compilation, and the status of the serve command is not clear.

Steps To Reproduce

Steps to reproduce the behavior:

1. Installed dx with cargo install dioxus-cli (0.5.4 on crates.io)
2. Created a new Dioxus application

> dx new
✔ 🤷   Which sub-template should be expanded? · Fullstack
🤷   Project Name: releasetool
✔ 🤷   Should the application use the Dioxus router? · true
✔ 🤷   How do you want to create CSS? · Vanilla

3. run: cd releasetool
4. run: dx serve

Output in gist (too long for github issue): https://gist.github.com/foresterre/3630ef11472c4fdc1523af2397f73818

Expected behavior

Observed effects:

• Panic after "Waiting to start building the project..."
  • -> A panic is usually not a good signal

stack backtrace:

• It seemed like the build hung on the latest step: / ⚙️ Compiling releasetool 0.1.0 (I killed it after 10 minutes), but in hindsight, it might have completed compilation since this is the serve command 😅
  • I expected the status of serve to be clear, so I can act accordingly
  • It wasn't clear immediately whether something still was going on, or whether something had failed, or whether the build was actually completed
    • Whether still going on: The tool shows a long compilation log, not dissimilar to cargo build, but the latest "compiling" step is never shown to have completed. This makes sense with respect to all other "compiling" steps, but since this command (serve) is intended to run forever, it could be useful to also show whether the step was completed, not just made some form of progression
    • Something has failed: in the middle of the compilation log, something panicked, but the build went on: I wasn't sure when the program seemed to hang, whether that was causing it (or whether it actually could continue)
    • Whether the build completed: since this is the serve command, it may very well have succeeded regardless, but only in the middle of the wall of logs you will find this:

• Dioxus version: 0.5.0

Questionnaire

• I'm interested in fixing this myself but don't know where to start
• I would like to fix and I have a solution
• I don't have time to fix this right now, but maybe later

The underlying bug is a duplicate of #2090 but the TUI is admittedly not very clear. However, we've totally revamped how do we the CLI and should be better and catching and relaying panics.
