Add "Copy hosts (JSON)" and "Copy hosts (TSV)" buttons for host list views

Browse source 
Adds two buttons to the view.py menu bar that copy hostname (FQDN) and
IP for every host on the page to the clipboard, as JSON or as
tab-separated lines. Works on views grouped by folder across multiple
tables as well as single-table views, and correctly handles views that
render 2 hosts per physical row as side-by-side column pairs.

### Copy Hosts (JSON/TSV)
Adds **"Copy hosts (JSON)"** and **"Copy hosts (TSV)"** buttons to the menu bar on any monitoring view listing hosts (e.g. "Host search"), whether results are grouped by folder across several tables or shown as a single table. Clicking one copies hostname (FQDN) and IP for every host currently listed to the clipboard — deduplicated — either as a JSON array or as tab-separated `FQDN` / `IP` lines (with a header row) ready to paste into a spreadsheet.
Applies to: any `view.py` page listing hosts (with or without sidebar).
## How it works
The script injects enhancements at page load and re-applies them on SPA navigation (Checkmk reloads content inside an `<iframe>` without a full page reload). Each feature is independent — a feature that does not apply to the current page does nothing and stops polling.
