Instead of showing all 4 billing providers as separate full-width cards,
the billing section now shows:
- When no billing connected: a compact 4-column grid picker to select
your billing platform (Gaiia, Sonar, Splynx, VISP)
- When one is active: a single card showing the connected provider with
status, sync info, and a note to disable before switching
This reduces visual clutter since users only ever use one billing system.
Non-exclusive categories (QoE, Incidents, Infrastructure) remain as
individual cards since multiple can be active simultaneously.
- Billing subscription and inventory item status fields are scalars, not objects
- IP blocks use "block" key, not "subnet"

- Handle empty string response from Preseem scores endpoint
- Fix CLOAK_KEY placeholder in nix shell (invalid base64)
- Fix error HTML test assertion to match actual template
- Fix Gaiia sync: read 'subnet' field instead of 'block' for IP blocks
- Fix Gaiia sync: extract nested status name from subscription objects
- Fix security headers tests for environment detection
- Fix mobile auth tests to use raw_token
- Fix LiveView test assertions to match actual template content
- Fix SNMP config test expectations for test environment
- Refactor: resolve all Credo complexity/nesting issues
- Extract helper functions in NetBox sync, VISP sync, Sonar sync
- Flatten nested conditionals in settings, integrations, alerts
- Use with/validate_present pattern for connection testing
