Read-only text values in Settings should be copyable (e.g. Port in Running details)

## Problem

Read-only values displayed in the Settings pane cannot be selected or copied. The most common case is the **Port** row under "Running details" - to connect an external tool or open the URL manually, the user has to read the number off the screen and retype it.

## Expected

Informational text values in Settings (and similar detail panes) should be copyable. Either:

- make the text selectable so standard copy works, and/or
- add a small copy-to-clipboard affordance (icon button) on hover for value rows like Port, install path, etc.

## Scope

- Port in Running details is the motivating example.
- Audit other read-only value rows in the Settings pane (paths, versions, URLs) and apply the same treatment consistently.

Locate the Settings pane and the Running details Port row, then trace how read-only values are rendered and how clipboard actions are handled elsewhere. Audit the other paths, versions, and URLs mentioned in the issue; done means those values can be copied consistently and the relevant UI checks pass.
