feat(app): tip jar (StoreKit consumables) in Settings -> About

Browse Source 
Four consumable IAP tiers - Small (0.99), Medium (2.99), Large (4.99),
Generous (9.99), product ids com.psmattas.OutpostApp.tip.{small,
medium,large,generous}. TipJarStore loads them via
Product.products(for:), purchases via product.purchase(), finishes
the transaction immediately on success - consumables have no
entitlement to persist or restore (a tip doesn't unlock anything), so
there's none of the Transaction.currentEntitlements restore-on-launch
logic a real purchase would need. TipJarView shows one button per
tier (price + name, StoreKit's own localized display strings) with a
"Thank you!" after success or a plain message on failure - no manual
retry button, tapping a tier again just re-attempts.

Wired into AboutInfoView between the source link and the copyright
line.

Added Configuration.storekit (4 products matching the IDs above) for
local testing in Xcode without needing real App Store Connect
products yet - enable it via Edit Scheme -> Run/Preview -> Options ->
StoreKit Configuration. Before actually shipping, the same 4 product
IDs need to exist for real in App Store Connect (Consumable type,
matching reference names) - the local file doesn't create anything
there.

Not compiler-verified - Outpost app target has no CLI build path.
