fix(traefik): Remove conflicting TCP router for subdomain handling

The TCP router was intercepting wildcard subdomain traffic at the TCP layer
and sending it directly to nginx:80, bypassing HTTP routing entirely.
This caused 404 errors because nginx wasn't receiving proper HTTP routing.

Now relying on:
- TLS store's defaultGeneratedCert for wildcard certificate
- HTTP HostRegexp router for subdomain routing to nginx
