power: full trial-to-paid journey in the Account card

The Power build IS the full app — when a trial ends the voice service just
gates off (daemon _voice_gate_open keys on plan=='power') and narration keeps
working; nothing is 'cut off' and there's no separate Pro app to download.
Paying re-enables voice in place.

_powerUpsell() renders one block with four states so the journey reads in one
place:
- trialing        → 'Upgrade to Power … N days left' + monthly/annual
- trial ended/Pro → 'back on Pro, add Power' + monthly/annual
- trial ended/Free→ 'Power for voice, or Pro for cloud voices' + Pro option
- never trialed   → 'Try Power free'
Needs a power_trial_used signal to tell 'ended' from 'never trialed'; synced
from /v1/me via _sync_plan_from_me. All 9 states verified.
