fix: configure netdata to use Slack-compatible webhook for Mattermost

Browse Source 
Netdata v2.7 doesn't natively support Mattermost notifications, but
Mattermost supports Slack-compatible webhooks. Changed configuration to
use SEND_SLACK with SLACK_WEBHOOK_URL pointing to the Mattermost webhook.

Configuration changes:
- Changed SEND_MATTERMOST="YES" to SEND_SLACK="YES"
- Changed MATTERMOST_WEBHOOK_URL to SLACK_WEBHOOK_URL
- Updated role_recipients_mattermost to role_recipients_slack
- Webhook URL still uses ${MATTERMOST_WEBHOOK_URL} env var from .env

Tested with: alarm-notify.sh test
Result: All three alarm types (WARNING, CRITICAL, CLEAR) show "OK"
