fix: display logo image instead of initials in custom template (#222)

[sivamurugan90428]

Summary

This PR fixes issue #222 — in custom presentation templates, the logo was previously displaying a fallback "i" even after replacing the logo URL.

Now, dynamicSlideLayout.tsx renders the logo as an element when a valid image_url is provided, and falls back to initials only if no image exists.

Changes

• Added dynamicSlideLayout.tsx under servers/nextjs/presentation-templates/custom/
• Updated README.md with instructions for updating logos in custom templates
• Ensured proper rendering of left and right brand logos in the header section
• Maintained decorative waves at the bottom

Testing

• Verified locally using npm run dev
• Confirmed that providing a valid image_url renders the logo image instead of "i"
• Confirmed fallback to initials still works when no image URL is provided

Notes

This update allows template creators to easily replace placeholder logos with custom images and ensures consistent display across templates.
