"Update" instead of "Install" on the dashboard

**Describe the problem you have/What new integration you would like**

I understand that it makes sense to use simpler terms, but using "install" after the first setup for an already installed device doesn't make that much sense IMHO (on the device list and especially in the editor).
This could also confuse the user, because he might wonders why he has to install the firmware again, although he has already done so.

I'd propose "update" as a simple and well known term, which IMHO fits better after the first installation.

**Please describe your use case for this integration and alternatives you've tried:**

**Additional context**

Start by locating the dashboard's device list and editor entry points where the "Install" label appears. Check how the label is used after initial setup and confirm that the requested wording applies to those contexts; done means the relevant post-installation actions display "Update" without changing the initial installation wording.
