* Decode reward payload in RewardVerification poll response (#6678)

* Decode reward payload in RewardVerification poll response

Plumbs the verified-reward payload from the backend response through the
internal `pollRewardVerificationStatus` SPI so RC ad adapters can dispatch
meaningful "verified" events with the granted reward.

* Adds `VirtualCurrencyReward` and `VerifiedReward` (`@_spi(Internal) public`)
  under `Sources/Ads/RewardVerification/`.
* Extends `RewardVerificationStatusResponse` to optionally decode a typed nested
  reward payload (`{ type, code, amount }`) on `verified` responses.
  - `reward` absent or null → `.noReward`
  - `type == "virtual_currency"` with valid `code`+`amount` → `.virtualCurrency`
  - any other `type` (or malformed `virtual_currency`) → `.unsupportedReward` + warn
* `RewardVerificationPollStatus.verified` now carries the `VerifiedReward`.
* `Purchases.pollRewardVerificationStatus` returns `.verified(reward)`.
* Test mocks injected via a new `BasePurchasesTests.MockBackend` convenience
  init so `backend.adsAPI` resolves to `MockAdsAPI`.

* Add unit tests for VerifiedReward and VirtualCurrencyReward

Co-locates the unit tests next to the types this PR introduces under
`Sources/Ads/RewardVerification/`:

- `Tests/UnitTests/Ads/RewardVerification/VirtualCurrencyRewardTests.swift`
  Covers field storage, equality (both fields must match), and decimal
  precision preservation.

- `Tests/UnitTests/Ads/RewardVerification/VerifiedRewardTests.swift`
  Covers `.virtualCurrency(_)` associated-value carrying, `.noReward`
  vs `.unsupportedReward` distinct-case identity, equality (matching
  associated reward required), and an exhaustive switch coverage test
  to guard against silently adding cases.

Both tests pass against the existing `Sources/Ads/RewardVerification/`
types and require no changes to them.

(Originally written on top of #6663; moved to this base PR so the type
and its tests ship together rather than splitting across PRs.)

* fix: warn when reward verification reward value is not a JSON object

Previously, `decodeVerifiedReward` silently returned `.noReward` for any
of: missing reward key, null reward, or non-object reward value (e.g. a
string/number/array). The first two are expected; the last indicates a
backend mismatch and should be surfaced.

Now distinguish:
- absent or null reward → `.noReward` (silent, expected)
- present but not a JSON object → `.unsupportedReward` + `Logger.warn`

This matches the existing convention in this file of logging warnings
when decoding unrecognized/malformed values into fallback cases.

* Fix virtual currency reward amount type to integer.

Align reward payload modeling with backend semantics by decoding `amount` as Int and updating tests to reject fractional values as malformed rewards.

* fix: address review — couple verified status to reward

Make the reward payload part of the verified status case so invalid state combinations are unrepresentable and remove the verified fallback mapping.

* fix: address review — reject non-positive reward amounts

Treat virtual-currency rewards with non-positive amounts as malformed payloads and return unsupported reward with warning logs.

* fix: address review — reject empty reward currency code

Validate virtual-currency payloads require a non-empty code and treat empty code values as malformed unsupported rewards.

* fix: address review — remove non-actionable enum switch test

Drop the exhaustive switch smoke test in VerifiedRewardTests since it did not validate behavior and duplicated compiler guarantees.

* fix: address review — remove synthesized equatable assertions

Drop VerifiedReward tests that only mirrored compiler-synthesized Equatable behavior and keep behavior-focused coverage.

* Delete claude.yml workflow (#6688)

* Add workflowTrigger to ButtonComponent.Action (#6693)

* Add workflowTrigger case to ButtonComponent.Action

Mirrors Android's rename of Action.Workflow → Action.WorkflowTrigger
(purchases-android#3380). Decodes backend "type": "workflow" into
.workflowTrigger so workflow buttons are rendered (previously decoded
as .unknown and hidden) and track as "workflow_trigger" in analytics.

* Cache decoded images by file URL in `FileImageLoader`

`URL.asImageAndSize` (used by `FileImageLoader.loadFromCache`) previously
called `UIImage(contentsOfFile:)` / `NSImage(contentsOfFile:)` on every
access. A SwiftUI paywall with many `RemoteImage` instances (e.g. a looping
carousel that materialises multiple copies of each page) ends up hitting
this path hundreds of times because `StateObject(wrappedValue:)` evaluates
its closure on every host view re-init. UIKit/AppKit's internal caches
still cost ~0.5–1 ms per call, which adds up to ~100+ ms of main-thread
blocking for only a handful of unique URLs.

Introduce a process-wide `DecodedImageCache` backed by `NSCache<NSURL, _>`
so repeated lookups for the same URL become a dictionary hit. `NSCache`
evicts on memory pressure, so we don't pin images forever. Reads/writes
are serialised through a concurrent dispatch queue with a barrier on
writes to keep the cache thread-safe.
