fix(smart-plugs): select printer power deterministically

[ichwars]

Summary

• use one deterministic printer-power ranking for the printer card, queue power-on, and per-print energy accounting
• prefer switchable, explicitly assigned, enabled and measurable power rows while retaining script-only fallbacks and accessory automation
• never bill a metered accessory when the selected printer outlet has no lifetime counter; log missing measurements instead
• extract the shared rule from size-limited consumers and lower their grandfathered source budgets

Related Issue

Closes #140

Documentation

• No docs update required — this fixes internal smart-plug selection without changing configuration or workflow

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• Code refactoring
• Test addition or update

Upstream comparison

Selectively adapts the deterministic smart-plug selection behavior from maziggy/bambuddy commits 5a05e03 and 9a2b811. PrintOps' per-plug accessory/dryer automation and active-print auto-off protection remain unchanged; energy fallback is intentionally stricter so accessory meters cannot be attributed to printer consumption.

Testing

• Issue regression suite: 34 passed
• Smart-plug, energy, manager, and archive regression selection: 209 passed
• Full backend: 8,593 passed, 253 skipped
• Full frontend: 3,041 passed across 267 files; all 11 locales in parity
• Frontend lint, TypeScript typecheck, and isolated production build
• Ruff lint/format, source-size budget, dependency boundaries, compile check, domain guard, and diff checks

Checklist

• My code follows the project's coding style
• My changes generate no new warnings
• I have tested my changes thoroughly
• No protected PrintOps business-domain behavior was removed

Hardware note

No printer-hardware test was performed. Tasmota, Home Assistant switches/scripts, MQTT monitors, REST capability ranking, disabled rows, multiple metered rows, accessory preservation, and missing-counter behavior are covered by automated tests.
