Standardize Terminology: Replace ‘Devices’ with Remote Instances Across FlowFuse

### Description

**Purpose**

We currently use multiple overlapping terms Devices, Remote Instances,—across the product, documentation, and marketing/blog content. This inconsistency causes confusion for users and creates technical and documentation debt.

**Goal:**

Standardize all user-facing terminology to Remote Instances across:

- Product UI – pipelines, device groups, dashboards, and settings.
- Documentation – guides, tutorials, and reference material.
- Blog & Marketing Content – articles, announcements, and tutorials.
