Clément Désiles 5efc0b0d6e fix(nginx): make Let's Encrypt opt-in per service
certbot cannot issue for internal hostnames (*.nas.local), which made
nginx-enabled services with internal names fail on deploy.

Add a <service>_nginx_letsencrypt flag (default false) and computed
<service>_nginx_ssl_certificate/_key paths: when off the vhost uses the
shared self-signed cert (nginx_default_ssl_cert), when on it uses the
Let's Encrypt lineage. Gate the certbot include on the flag and apply the
pattern to all service roles (deluge, fdroid, gitea, grafana, immich,
metabase, ntfy, prowlarr, radarr, seerr, static_web, uptime_kuma).

# Radarr Role
Deploys [Radarr](https://radarr.video/) - a movie collection manager for Usenet and BitTorrent - using Podman with k8s files. The `linuxserver/radarr` image bundles Radarr and its SQLite database.
## Prerequisites
The `podman` role must have been applied to the host first. Order it before `radarr` in the playbook for fresh installs.
## Role Variables
See `defaults/main.yml` for all available variables and their default values.
## Storage
- `radarr_config_dir` - SQLite database, library and API keys. Backed up.
- `radarr_movies_dir` - movie library, mounted read-write at `/movies`. Use `/movies` as the root folder in the Radarr UI.
- `radarr_downloads_dir` - completed downloads, shared with Deluge. Mounted read-write at `/downloads`; point the download client there.
`radarr_movies_dir` lives on ZFS (`/mnt/andromeda`), `radarr_downloads_dir` under `{{ podman_projects_dir }}` - cross-filesystem imports are copies, not hardlinks.
## Ports
| Port | Protocol | Purpose |
| ---------------------- | -------- | ------- |
| `radarr_port` (7878) | tcp | Web UI |
## Nginx Reverse Proxy
Set `radarr_nginx_enabled: true` and `radarr_nginx_hostname` to expose the web UI over HTTPS. TLS is opt-in:
- `radarr_nginx_letsencrypt: false` (default) — use the shared self-signed cert (`nginx_default_ssl_cert`, generated by the `nginx` role). Required for internal names like `*.nas.local`, which Let's Encrypt cannot issue.
- `radarr_nginx_letsencrypt: true` — provision a Let's Encrypt cert via the shared `nginx` role's certbot tasks. Requires a publicly-resolvable hostname with a DNS record pointing at the host.
## Backup
The role exposes `radarr_backup_paths` (config only). Add a job in the host inventory to include it:
```yaml
backup_jobs:
- name: radarr
repositories: [next_s3]
paths: "{{ radarr_backup_paths }}"
```
## Troubleshooting
```sh
systemctl --user status radarr
journalctl --user -u radarr -f
podman logs radarr
```
