Round 9: Homepage variable replacement and additional stack deployment

Features added:
✅ Homepage config variable replacement - Fixed HOMEPAGE_VAR_DOMAIN substitution
  - Homepage doesn't support environment variables in configs
  - Deploy script now uses sed to replace {{HOMEPAGE_VAR_DOMAIN}} with actual domain
  - All homepage/*.yaml files processed after template copy

✅ Additional stacks deployment to Dockge
  - 7 additional stacks now copied to /opt/stacks/: media, media-extended,
    homeassistant, productivity, monitoring, utilities, alternatives
  - Stacks are NOT started automatically - user deploys via Dockge UI as needed
  - Optional image pre-pull with user prompt (defaults to no)
  - Significantly improves first-time Dockge experience

✅ Watchtower temporarily disabled
  - Documented Docker API v1.44 compatibility issue with Docker 29.x
  - Added clear instructions for re-enabling when issue is resolved
  - Infrastructure stack now deploys 6 services (was 7)

Deployment workflow:
1. Core stack (4 services) - DuckDNS, Traefik, Authelia, Gluetun
2. Infrastructure stack (6 services) - Dockge, Pi-hole, Dozzle, Glances, Docker Proxy
3. Dashboards stack (2 services) - Homepage (configured), Homarr
4. Additional stacks (7 stacks copied, not started)

Tested: All 11 active containers healthy, all stacks visible in Dockge
