feat(firewall): enhance firewall management with community selection and script handling
Added a community selection feature to the firewall rules management UI, allowing users to specify BGP communities for block/accept policies. Updated the backend to support reading firewall scripts from a specified directory, improving script management. Enhanced documentation to clarify the new community functionality and its implications for firewall rules. Additionally, introduced tests for the firewall script endpoints to ensure proper functionality.

# Firewall blocklist
Подсистема синхронизации blocklist на произвольные Linux-серверы через bash-скрипт и HTTP API.
## Авторизация
1. **Enroll**`POST /v1/firewall/enroll` с заголовком `X-EvoBGP-Seed` (значение `EVOBGP_BUNDLE_SEED_HEX` на CP). Клиент генерирует токен `evobgp_fw_*` локально.
2. **Approve** — operator в Web UI (`/firewall` → Запросы).
3. **Sync**`GET /v1/firewall/blocklist` с `Authorization: Bearer <client_token>`.
## Политика block/accept
- **`block`** — добавить префиксы выбранного BGP community в kernel blocklist.
- **`accept`** — не блокировать префиксы этого community.
- **Community** — правило применяется к префиксам с этим `community_id` в опубликованной revision; пустое значение («Все») — ко всем communities.
- **Default** — accept (пустой blocklist без явных `block`).
Порядок: сначала per-server overrides клиента, затем tenant-default. Для каждого community берётся первое подходящее правило по приоритету.
Справочник communities: Web UI → Справочники, или модули с привязкой community к префиксам.
## Установка на сервер
```bash
curl -fsSL https://<api>/v1/firewall/install.sh | \
EVOBGP_CP_URL=https://<api> \
EVOBGP_SEED=<bundle_seed_hex> \
EVOBGP_CLIENT_NAME="web-01" \
bash
```
Файлы: `/etc/evobgp/firewall.conf`, `/usr/local/sbin/evobgp-firewall.sh`, systemd timer `evobgp-firewall.timer`.
## Failover через speaker
При `EVOBGP_FIREWALL_FAILOVER_ENABLED=1` на speaker-agent CP реплицирует состояние через `POST /v1/agent/firewall-replicate`. Клиенты используют тот же DNS-домен.
