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).

# Prowlarr Role
Deploys [Prowlarr](https://prowlarr.com/) - an indexer manager/proxy for the *arr stack - using Podman with k8s files. The `linuxserver/prowlarr` image bundles Prowlarr and its SQLite database.
## Prerequisites
The `podman` role must have been applied to the host first (shared service, intentionally not declared in `meta/main.yml` to keep prowlarr deploys fast). Order it before `prowlarr` in the playbook for fresh installs.
## Role Variables
See `defaults/main.yml` for all available variables and their default values.
## Storage
- `prowlarr_config_dir` - SQLite database, indexer definitions and API keys. Backed up.
## Ports
| Port | Protocol | Purpose |
| ------------------------ | -------- | ------- |
| `prowlarr_port` (9696) | tcp | Web UI |
## Nginx Reverse Proxy
Set `prowlarr_nginx_enabled: true` and `prowlarr_nginx_hostname` to expose the web UI over HTTPS. TLS is opt-in:
- `prowlarr_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.
- `prowlarr_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 `prowlarr_backup_paths` (config only). Add a job in the host inventory to include it:
```yaml
backup_jobs:
- name: prowlarr
repositories: [next_s3]
paths: "{{ prowlarr_backup_paths }}"
```
## Troubleshooting
```sh
systemctl --user status prowlarr
journalctl --user -u prowlarr -f
podman logs prowlarr
```
