Name conventions

[torabi12]

Describe the bug
I created a "D-Link" vendor in EMBArk but the test did not start, because the name contains hyphen, which is blocked by EMBA.
I tried to start the same test without selecting the existing vendor but the test also did not start. I created again a new scan with DLink vendor and it worked fine:

To Reproduce
Steps to reproduce the behavior:

1. EMBArk installation default-mode
2. Start EMBArk: sudo ./run-server.sh -a
3. Use the firmware available here: anything
4. Create a vendor or device with a non supported character and assign it to the FW file and try to start the scan.
5. There is no error, the test stops after a few seconds.

Expected behavior
EMBArk should warn the user and only the supported characters would be accepted on the page.

Screenshots
See above.

Desktop (please complete the following information):

• OS: Ubuntu Server 22.04.1

we need to adjust these filters. As quick fix I have included further allowed characters (-_) in EMBA.
