Avoid duplicated metadescriptions

[DH-555]

What does this PR do?

Uses custom descriptions for those pages instead of using the default metadescription.
Using the same is bad for SEO and not a good practice.

Greptile Summary

This PR replaces the generic DEFAULT_DESCRIPTION with unique, page-specific meta descriptions on the Partners and The Appwrite Network pages to improve SEO. The change is minimal and correct — Svelte properly escapes the <50ms string in the network page description when rendering it as an HTML attribute.

Confidence Score: 5/5

Safe to merge — only two lines changed and the logic is straightforward.

Both findings are P2 style suggestions (unused imports); there are no correctness, logic, or security issues.

No files require special attention.
