add desec (#7995)

## Summary
- Integrates Desec into the AIO interface which simplifies the domain
registration and domain setup.
- You can either create a new account directly or use an existing
account.
- You have a button that you can open where the process will be done.
After the process is done, the whole page reloads and you can continue
with the setup.
- Caddy and dnsmasq community containers will be activated during the
process which will take over the cert generation and enable split-brain
dns.
- Community containers will work automatically for example Vaultwarden
as the subdomains of the desec domain point automatically via a wildcard
dns entry towards the main desec domain.
- Playwright tests are added to ensure that the system works as expected
in the future
- the desec api is mocked via a small node js based file.
- the qa and other docs were updated to mention desec
