VS-06 Authorization Gate v1 (Free vs Premium)

[CherryClairette]

What to build

Deliver frontend authorization gating for free versus premium experience. This includes feature visibility control, gated actions, and user-facing upgrade messaging while keeping validation assumptions compatible with server-side enforcement.

Acceptance criteria

• At least one premium feature is hidden or disabled for free users
• Premium users can access gated feature without UI workarounds
• Free users see clear, non-intrusive upgrade messaging
• Permission state updates are reflected after session refresh
• Authorization behavior is covered by tests for free and premium roles
