#39503 chore(rest): migrate /api/v1/users.getPresence to OpenAPI endpoint definition

Migrates the users.getPresence REST API endpoint from the legacy API.v1.addRoute pattern to the new chained API.v1.get() pattern with AJV response schema validation and OpenAPI documentation support.

Endpoints migrated

Endpoint	Method	Old Pattern	New Pattern
users.getPresence	GET	addRoute	.get() chained

Architectural changes

• Replaced legacy API.v1.addRoute('users.getPresence', ...) with the new chained .get('users.getPresence', ...) method
• Added 400, 401 error response schemas using validateBadRequestErrorResponse and validateUnauthorizedErrorResponse
• Added AJV response schema for 200 response with presence, connectionStatus, and lastLogin fields
• Added query: undefined explicitly as per new pattern guidelines
• connectionStatus and lastLogin are optional — only returned for own user requests
• lastLogin serialized as ISO string for JSON compatibility

Files changed

• apps/meteor/app/api/server/v1/users.ts — Main migration
• .changeset/migrate-users-getPresence-openapi.md — Changeset entry
• packages\rest-typings\src\v1\users.ts — Remove old manual typing
