Bookshelf (PR #122) is a Readarr revival and now owns port 8787 on
london-b, so the old custom Readarr systemd unit is removed:
- drop readarr from the media_stack role's unit-deploy and enable loops,
and add an idempotent decommission task (stop, disable, remove unit)
so the host tears it down via Ansible rather than ad-hoc SSH
- delete services/readarr/readarr.service
- update docs (services, london-b host, service inventory) to describe
bookshelf as a Docker service instead of a custom systemd unit
The public readarr.pez.sh hostname is kept and now reverse-proxies to
bookshelf on :8787 — DNS, Caddy and Authelia (pez_readarr_users group)
are unchanged.
Sonarr is running on london-b as an apt-managed systemd service
but was the only *arr service without a services/ directory in the
repo. Add services/sonarr/README.md documenting the install method,
data paths, and how it differs from the other *arr services.
Closes PESO-133
