Closes#8305
The Clipboard API (`navigator.clipboard`) requires a secure context
(HTTPS or localhost). Self-hosted deployments on plain HTTP silently
fail when copying.
This PR:
- Adds a `document.execCommand('copy')` fallback for insecure contexts
- Shows a descriptive error message explaining HTTPS is required when
the fallback also fails
- Consolidates 3 components that were using `navigator.clipboard`
directly (without error handling) to use the centralized
`useCopyToClipboard` hook

<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Low Risk**
> Scoped to frontend clipboard UX with a defensive fallback and clearer
errors; minimal impact outside copy flows.
>
> **Overview**
> Improves copy-to-clipboard behavior in non-HTTPS/self-hosted
deployments by enhancing `useCopyToClipboard` to use
`navigator.clipboard` only in secure contexts and otherwise fall back to
`document.execCommand('copy')`.
>
> Updates 2FA setup screens and the view visibility dropdown to use the
centralized `copyToClipboard` helper (with consistent snackbars), and
shows a more descriptive error (longer duration) when copying fails due
to an insecure context.
