Summary: Competely adds tiered pricing plans

Why It Matters: The product is moving from a single discount offer to a structured subscription model. This defines clear limits on how many competitors and projects a user can track at different price points.

What Changed:

• Added a "Startup" plan for $39 per month.
• Added an "Agency" plan for $69 per month.
• Introduced an annual billing option with a 25% discount.
• Defined specific usage limits for projects, competitors, and analysis runs.
• Removed the detailed footer links and user navigation menu from the main page view.
