fix: gate captureException on user consent and fix HEIC PII scrubbing

captureException now checks isRequestOptedIn before forwarding errors to Sentry, closing a gap where server errors leaked to an external service even when no user had consented. The PII scrubbing regex is also fixed: he[ic]f? failed to match .heic due to word-boundary behavior and is replaced with hei[cf]? which correctly covers .heic, .heif, and .hei. Adds 88 new analytics tests across unit, integration, and e2e layers proving PostHog/Sentry are never invoked when analytics is disabled or users have not consented, plus full 7-day reminder lifecycle coverage.

+// The fix changed `he[ic]f?` to `hei[cf]?` so .heic and .heif are matched.
