UserProfileIds Provider

FutureProvider that fetches the authenticated user's customer ID (always) and seller ID (only when role==freelancer) in parallel and returns both. currentCustomerIdProvider selects the active one based on role — consumed by the cart, wishlist, and post-author scoping.

1. Watches authStateProvider; bails to empty when !isLoggedIn.
2. Spawns UserService.getClientInfo + (if freelancer) VendorService.getSellerProfile in Future.wait.
3. currentCustomerIdProvider re-reads userProfileIdsProvider + role and returns sellerId or customerId.
4. sellerProfileRawProvider exposes the full raw seller payload (used by trades/metiers UI).
5. currentSellerTradesProvider derives the métier list from the raw seller via parseSellerTrades.

• Clients NEVER hit /vendor/sellers/me — the role gate exists specifically to suppress 2 wasted 401 requests per home boot.
• Both fetches swallow their own errors so a failure in one branch doesn't blank the other.
• AuthState equality override (see auth feature) prevents userProfileIdsProvider from refetching on every login-flag tick.

Several other features (cart, wishlist) take a hard dependency on currentCustomerIdProvider — keep its semantics stable.
