Add Columns dropdown and merge export buttons into a menu

Browse source 
Adds a per-column ON/OFF toggle list (with Show all/Hide all) for
native monitoring table columns, replacing the earlier scattered
approach: hiding State also tints the service name with its state
color. Also consolidates the Markdown/host export buttons into a
single Export menu to keep the bar from growing too wide.

### Service Export to Markdown
On any monitoring view showing a services table — detected structurally by a **Host** column plus a **Display name**/**Service** column, not tied to one specific view — adds an **"Export to Markdown (.md)"** button to the menu bar. It turns the visible table into a standard Markdown table, one row per service, copies it to the clipboard and downloads it as a `.md` file in one click. Columns are Site, Host, IP, Display name, Summary, Details in that order, but only the ones actually present on the current view are included — a view without a Details column simply won't have one in the export. Rows are read at click time, so the export always matches what's currently on screen.

Applies to: any `view.py` page with a services table (with or without sidebar).

### 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.

### Column Visibility Toggle
Adds a **"Columns"** dropdown to the menu bar on any monitoring view table. Each entry hides/shows one native Checkmk column — State, Site alias, Host icons, Service icons, Checked, Check command, Groups (service + host) — found by its header text, so it works on any view without being tied to one specific one. Only the columns actually present on the current view are listed, each with its own **ON/OFF** button so it's always clear at a glance what's currently shown, plus **"Show all"**/**"Hide all"** shortcuts at the top of the panel to reset everything in one click. Purely visual (CSS only, never touches form/checkbox state), and the choice is saved so it applies the same way to every monitoring view you open afterwards.
Hiding the **State** column also tints the service name itself with that row's state color (green OK, amber WARN, red CRIT, purple UNKNOWN), so problems stay identifiable at a glance without the column taking up space.
Applies to: any `view.py` page with a data table (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.
