Add PageStrike to Landing Pages

[Youssefroop]

What this PR adds

Adds PageStrike to the Landing Pages section, alphabetically inserted between Leadpages and Pagewiz.

Why it fits

PageStrike is an AI-first landing page builder. Differs from existing entries in the section:

• Convertkit / GetResponse / Leadpages — primarily email-marketing platforms with bolt-on landing pages. PageStrike is landing-page-first.
• Carrd / Unbounce / Instapage — manual builders requiring template selection + copywriting. PageStrike's AI generates the complete page (copy + photos + form) in under 2 minutes from a 1-sentence product description.

Unique differentiators not present in any other entry:

• Native cash-on-delivery checkout pipeline (MENA / Africa / SEA markets)
• 0% commission on Stripe/PayPal direct
• Native AI generation in 10+ languages including Arabic RTL
