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.
