feat(landing): Sentry pricing guide - #1570

🟢 Confidence 10/10 · safe to merge
The only open finding was the missing screenshots, now added with paths and intrinsic dimensions that match the two <img> tags.
_{no findings · tests not needed · risk low}

The head commit adds the two Maple screenshots the Sentry pricing guide renders and renames the second reference to match, which closes the earlier missing-image finding. The guide's content is unchanged and safe to merge.

• Both guide-figure images now exist under apps/landing/public/screenshots/guides/
• The second figure points at sentry-pricing-02-occurrences.webp, whose alt text describes the Occurrences tab

Fixed since the last review

• ✅ F1 · Both guide-figure screenshots this guide references are not in the repo
