Allow multiple Home Assistant entities per printer (fixes #214)

Both frontend and backend were blocking printers that already had any
smart plug linked, preventing users from adding multiple HA entities
to the same printer.

Changes:
- Frontend: Only filter out printers with existing Tasmota plugs
- Backend: Only check for duplicate Tasmota plugs on create/update
- HA entities (switches, scripts, lights, etc.) can now be linked
  multiple times to the same printer for different automations
- Tasmota plugs remain limited to one per printer (physical device)
- Restored "Show on Printer Card" toggle for HA entities
- Fixed printer card only showing script.* entities; now shows all
  HA entities with the toggle enabled
- HA entities now default to auto_on=False and auto_off=False
- Printer cards now update immediately when HA entities change

Closes #214

### Fixed
- **Cannot Link Multiple HA Entities to Same Printer** (Issue #214):
- Fixed Home Assistant entities being limited to one per printer
- Both frontend and backend were blocking printers that already had any smart plug linked
- Now only Tasmota plugs are limited to one per printer (physical device constraint)
- Multiple HA entities (switches, scripts, lights, etc.) can be linked to the same printer
- Restored "Show on Printer Card" toggle for HA entities to control visibility on printer cards
- Fixed printer card only showing `script.*` entities; now shows all HA entities with toggle enabled
- HA entities now default to auto_on=False and auto_off=False (appropriate for automations)
- Printer cards now update immediately when HA entities are added/modified/deleted
- **Monthly Comparison Calculation Off** (Issue #229):
- Fixed filament statistics not accounting for quantity multiplier
- Monthly comparison chart now correctly multiplies `filament_used_grams` by `quantity`
