Fixes #1651

## Description

The `_processError` method in `purchases_flutter_web.dart` uses `error
is JSObject`, which triggers the
`invalid_runtime_check_with_js_interop_types` lint. The `is` operator on
JS interop types is unreliable under Wasm compilation because JS interop
types are erased differently between JS and Wasm targets.

This replaces the runtime check with the Wasm-safe `isA<JSObject>()`
method from `dart:js_interop` (available since Dart 3.4, and the project
requires Dart >=3.6.0).

- [x] A description about what and why you are contributing, even if
it's trivial.
- [x] The issue number(s) or PR number(s) in the description if you are
contributing in response to those.
- [x] If applicable, unit tests.

## Changes

**`lib/web/purchases_flutter_web.dart`**
- Cast `error` to `JSAny?` before checking
- Replace `error is JSObject` with `jsAny.isA<JSObject>()`
- Extract `jsObject` via `jsAny as JSObject` after the `isA`
confirmation
- No new imports needed (`dart:js_interop` is already imported)
- Identical runtime behavior to the original code

**`CHANGELOG.md`**
- Added bugfix entry under 9.14.0

## Test plan

- [x] `dart format .` — clean
- [x] `flutter analyze lib` — passes with no issues (the
`invalid_runtime_check_with_js_interop_types` warning is gone)
- [x] `flutter test` — all 134 tests pass
- [x] `cd revenuecat_examples/purchase_tester && flutter build web` —
web build verification
- [x] `cd revenuecat_examples/purchase_tester && flutter build web
--wasm` — Wasm build verification
- [ ] CI: `bundle exec fastlane run_api_tests` — no public API changes
(requires CI environment)

## Why no new unit tests

`_processError` is a private method that uses `dart:js_interop` types
requiring a web runtime. The repo has no web-platform test
infrastructure (`flutter test --platform chrome`), and the change is a
mechanical replacement of one pattern with its Wasm-safe equivalent.
`flutter analyze` statically catches the lint if it regresses. Adding
web test infra would be out of scope for this bugfix.

> [!NOTE]
> **Low Risk**
> Low risk: a small, localized change to web error parsing that should
only affect how JS/Dart exceptions are detected under dart2wasm and how
fallback `PlatformException`s are produced.
> 
> **Overview**
> Fixes web error processing to be **Wasm-compatible** by avoiding
`error is JSObject` checks in `_processError`.
> 
> Errors are now *safely* cast to `JSAny?` (catching `TypeError` under
dart2wasm) and validated via `isA<JSObject>()` before extracting
`code`/`message` details; non-JS errors fall back to the generic unknown
`PlatformException` path.

> [!NOTE]
> **Low Risk**
> Low risk release bookkeeping: primarily version bumps and
changelog/version-matrix updates, with no functional logic changes in
the plugin code beyond reporting the new version string.
> 
> **Overview**
> Updates the SDKs to **v`10.0.1`** by bumping version identifiers
across `pubspec.yaml`, Android Gradle configs, and iOS/macOS podspecs
(including the runtime-reported plugin version strings).
> 
> Refreshes release documentation (`CHANGELOG.md`,
`CHANGELOG-LATEST.md`, `VERSIONS.md`) to include the `10.0.1` notes
(Wasm web error-processing fix) and the dependency bump to
`purchases-hybrid-common` `18.1.0` (Android `10.2.0`, iOS `5.68.0`).
