CRAFT-1995: update @sentry to v8

[valoriecarli]

Existing @commercetools-frontend/sentry package is not compatible with react 19 and causing peer dependency conflicts. Official React 19 support was added in Sentry v8.

References:
https://commercetools.atlassian.net/browse/CRAFT-1995
#3879

Note that this PR intentionally keeps deprecated Sentry v8 types (Event, Extra, Extras) for now to minimize breaking changes.

---

1.) Upgraded the following Sentry packages from v7.120.4 → v8.55.0 and resolved breaking changes:
@sentry/react, @sentry/browser, @sentry/types

2. API Migration

// v7 (deprecated)
Sentry.configureScope((scope) => {  scope.clear();});

// v8 (new API)
Sentry.getCurrentScope().clear();

3. TS Fixes - Sentry v8 introduced stricter types for the beforeSend callback:

Issues:

• v8 requires both event and hint parameters
• Return type changed from Event to ErrorEvent | null
• Importing ErrorEvent from @sentry/types shadowed the global DOM ErrorEvent type

Resolutions:

• Aliased import as SentryErrorEvent to avoid name collision with DOM types
• Added _hint parameter (underscore prefix for intentionally unused param)
• Cast return type as SentryErrorEvent (safe since beforeSend only receives error events)

4.) Added a few tests to ensures the v8 API migration (configureScope → getCurrentScope()) works correctly.

@tylermorrisford good call. Updated the comment a bit to make it clearer, and noted it in the pr description as well. TL;DR - this was purely for type checking. Sentry v8's beforeSend requires both parameters in the signature, even if we don't need them (yet). v8 introduced a number of newly deprecated types that I started working on, but noped out to keep this minimal to focus on React 19 compatibility.
