feat: version history as 10th feature flag, richer upgrade prompts, close unguarded photo-import tab (v0.80.0)

Recipe version history is now gated like the other 9 per-tier features (enabled by default, locked-vs-hidden treatment via isFeatureAvailableAnyTier). UpgradeDialog now shows a tagline + concrete bullet list per feature instead of one generic sentence.

Also closes a real gap: the AI-generate dialog's Photo tab hit /api/v1/ai/import-photo directly with no tier check in the UI (server route was already correctly gated) — a locked-out user could fill it in and hit a dead-end error instead of an upgrade prompt. Now threaded through the same lock/hide props as the dedicated PhotoImportButton.
