fix: Remediate all Dokploy blueprint standard violations in Technitium DNS template
- Remove container_name fields (Dokploy forbidden) - Change restart policy to 'unless-stopped' (project standard) - Remove explicit networks definition (Dokploy manages) - Remove port 5380 HTTP exposure (admin access via Traefik HTTPS) - Add security headers middleware (HSTS, content-type-nosniff, frame-deny) - Fix rclone-backup sidecar configuration: - Replace bind mount with RCLONE_CONFIG_* environment variables - Improve shell variable quoting to prevent injection - Relax healthcheck logic (300s interval, less stringent matching) - Fix template.toml variable declarations: - Add missing PRIMARY_NODE_IP variable - Remove unused variables - Rename r2_account_id to cf_account_id for consistency - Add README section documenting DNS port 53 exception - Add SVG icon for template catalog Documentation: Explain that port 53 UDP/TCP is a documented exception required by DNS protocol, distinct from the general 'no exposed ports' rule. Clarifies that admin console (port 5380) is Traefik-routed HTTPS only.

## Network Requirements: DNS Port Exception
126+
127+
Technitium DNS Server requires **UDP/TCP port 53** for DNS queries from clients. This is a **documented exception** to Dokploy's "no exposed ports" rule because:
128+
129+
1. **DNS Protocol Fundamentals**: Unlike HTTP/HTTPS services routed through Traefik, DNS operates on its own protocol (port 53 UDP/TCP) without TLS encapsulation. DNS clients query port 53 directly and cannot be intercepted by Traefik.
130+
131+
2. **Admin Console Access**: The web admin console (`port 5380`) IS routed through Traefik with HTTPS/Let's Encrypt encryption. Only port 53 is directly exposed.
132+
133+
3. **Architectural Distinction**:
134+
-**Port 53 (DNS)**: Directly exposed (protocol requirement)
135+
-**Port 5380 (Admin)**: Traefik-routed HTTPS via domain
136+
137+
**Security Model**: Port 53 is secured by firewall rules and network isolation, not TLS. Configure your firewall to restrict port 53 access to trusted networks (internal mining sites, specific ISP ranges, etc.).
