web: Fix theme resetting to first theme in list (#156)

* examples: Add CoreDNS for *.local domain resolution

Adds a CoreDNS example that resolves *.local to the Traefik host,
making the .local routes in all examples work out of the box.

Also removes the redundant Multi-Container Stacks section from
README since paperless-ngx already demonstrates this pattern.

* examples: Add coredns .env file
