Your Taskboard now keeps a full history of changes — save snapshots, preview any past state, and roll back when things go off track:

• Save Versions: Take a snapshot of your entire Taskboard — tasks, columns, and labels — with a single click from the new History panel.
• Preview Past Versions: Browse any saved version in a read-only preview to compare what changed, without affecting your current board.
• Roll Back Anytime: Restore any previous version instantly. Rolling back creates a new version entry, so nothing is ever lost.
• Live Change Indicator: A dot on the History button tells you when your board has unversioned changes since the last save.
• Version Labels in Header: The current version number is displayed alongside the Taskboard name so you always know which snapshot you're on.

Upgrading to Pro is now a real subscription powered by Payment Gateway:

• In-App Checkout: The Plan upgrade modal now launches a secure Payment Gateway checkout for paid plans.
• Monthly & Yearly Pro Plans: Choose between monthly or yearly Pro subscriptions.
• Instant Verification: Payments are verified server-side before your plan is activated.
• Automatic Credit Top-Up: When you upgrade to Pro, your credits are immediately boosted to your new tier's allocation (e.g., 100 → 1,000).

Your billing status is now visible and manageable inside the app:

• Real Renewal Dates: The Profile subscription area shows your actual billing renewal date.
• Cancel Anytime: Cancel your subscription directly from the app — your Pro access continues until the end of the current billing cycle.

• Versions are preserved when navigating between ideas and taskboards.
• Undo/Redo actions now work alongside Taskboard versioning without conflicts.

• Fixed a theme-related hydration flash on the chat toggle icon.
