fix: remove interactive --password flag so Glances web server can start

The --password flag makes Glances prompt for a password interactively
via getpass, which fails in a non-TTY container. The container kept
crash-looping, so Traefik returned 404 for the domain. Glances also
does not read GLANCES_USERNAME/GLANCES_PASSWORD env vars, so the auth
setup was ineffective. Run the web server with GLANCES_OPT=-w and drop
the unused password env vars from the compose file and template.toml.
