Walkthrough

This PR consolidates PostGIS geometry documentation by removing dedicated files, simplifying extension guides, and clarifying current limitations for Prisma's extension type support. A minor CRUD documentation formatting issue is also corrected.

Changes

Documentation updates

Layer / File(s)	Summary
CRUD example code fence correction apps/docs/content/docs/orm/prisma-client/queries/crud.mdx	Code fence terminates properly in the "Filter by related records" section, allowing the "Filtering and sorting" reference link to appear after the complete code block rather than interrupting it.
PostGIS documentation consolidation and extension limitations apps/docs/content/docs/orm/prisma-client/special-fields-and-types/working-with-geometry-fields.mdx, apps/docs/content/docs/orm/prisma-schema/postgresql-extensions.mdx, apps/docs/content/docs/postgres/database/postgres-extensions.mdx	Removed working-with-geometry-fields.mdx file (984 lines), deleted the entire "PostGIS extension for spatial data" section from the Prisma schema extension guide, and updated the Limitations section to clarify that Prisma Studio cannot deserialize custom extension types (e.g., VECTOR) and Prisma ORM represents unimplemented extension types as Unsupported, requiring raw SQL for queries. The outdated "PostGIS is coming in 2026" claim is removed.
