Update the Pricing page with the new plans

Scope

• Current plan names, prices, and limits
• Feature comparison table kept accurate against what actually ships
• Annual vs. monthly toggle with the discount stated plainly

Acceptance criteria

• Every price matches billing configuration exactly — verified against the billing system, not against a spreadsheet
• Every feature claim is true today, not planned
• Currency and tax display correct for supported regions
• Reviewed by whoever owns billing before it goes live
