Improvements and Fixes

• Added an audit trail page to the end of documents that went through the Portal eSign flow to meet even the strictest eSignature criteria.
• Added empty state pages to all modules so the experience is better for internal users and client users when a module has no content (for example, no invoices or knowledge base articles).
• Added a tooltip to the icon that indicates which invoices are part of subscriptions
• Improved the look of headers on mobile screens.
• Improved several small UX details in the Forms module.
• Improved the rendering process on the messaging page; improving stability.
• Fixed spelling mistakes for intake forms email notifications.
• Fixed a bug where in-product messaging notifications didn't go away real-time.
