fix: validate simulator notification rules

[goanpeca]

Summary:

• Add simulator validation for bucket notification rule names, event types, isEnabled booleans, maxEventsPerBatch positive integers, webhook targets, HTTPS URLs, and unsupported fields.
• Reject invalid rules before storing them in b2_set_bucket_notification_rules.
• Narrow EventNotificationRule.targetConfiguration.targetType to 'webhook' and add optional maxEventsPerBatch typing.
• Update notification rule regression coverage and stale targetType docs.

Linked issue:

• Closes simulator: set_bucket_notification_rules performs no validation #17

• pnpm run typecheck
• pnpm run lint
• pnpm run lint:docs

Follow-up notes:

Pull request overview

This PR improves the simulator’s fidelity to the real B2 API by validating b2_set_bucket_notification_rules inputs (per Issue #17) so invalid notification rules are rejected before being stored/used, and updates related regression coverage and docs.

Changes:

• Added validateNotificationRules() in the simulator validation layer (names, event types, webhook target type, https URL, and unknown-field rejection).
• Wired the new validator into B2Simulator.setBucketNotificationRules so invalid rules return 400 instead of being stored.
• Added/updated unit + fidelity tests and corrected targetType documentation to reflect 'webhook'.
