* Capture Sentry errors prior to initialization Sentry errors captured before/during the wallet initialization are currently not captured because we don't have the controller state yet to determine whether the user has consented. The Sentry setup has been updated to check the persisted state for whether the user has consented, as a fallback in case the controller state hasn't been initialized yet. This ensures that we capture errors during initialization if the user has opted in. * Always await async check for whether the user has opted in * Remove unused import * Update JSDoc return type * Remove unused driver method * Fix metametrics controller unit tests * Fix e2e tests * Fix e2e test on Firefox * Start session upon install rather than toggle
