feat(stack): replace Organizr with Tatlock UI, remove Netdata

Remove Organizr dashboard and Netdata monitoring:
- Delete stacks/organizr.yml and stacks/netdata.yml
- Delete organizr-widgets/ directory and npm forward-auth config
- Remove organizr database references from postgres-shared docs

Promote Tatlock UI as primary dashboard:
- Move from port 8092 to 9999 (Organizr's port)
- Enable external access at home.schweitz.net
- Update all documentation references

Update service counts: 26 containers across 20 stacks

 - **docs/reference/CONTAINERS.md:** Document the service with full profile and configuration table
