Add a direct Biome-view shortcut button to the toolbar

Browse Source 
During Tectonics/Hydrology there was no direct way to see the world's actual
terrain type (deserts/forests/tundra/etc, colour mode Biome) -- the only
paths were opening the 13-entry View Mode dropdown, or an accidental side
effect of toggling Ecoregions off (which happens to land on Biome). Added a
one-click "Biome view (5)" button right under the dropdown, outside the
scrollable body so it needs no scrolling and is visible from the very start
of World Creation, before any Civilization & Ecology feature is relevant.

Verified live: fresh world, Tectonics phase, single click correctly switches
to Biome view showing deserts/forests/ice caps.

@ -422,6 +422,15 @@ on the Live World clock). **Steps 1–7 of the roadmap are done (plus a derived
"Alliances" checkbox in Overlays), `&&`-ed into just the ally/rival arc draw calls (3D + 2D) so
political borders/war fronts still show under Territory regardless — Territory now toggles cleanly
with or without the arcs. `src/render` only, no save-format change.
- **Toolbar: a direct one-click "Biome view" shortcut** *(done)* — during Tectonics/Hydrology (before
any Civilization & Ecology feature is even relevant) the only way to see the world's actual terrain
type (deserts/forests/tundra/etc., colour mode `Biome`) was to open the 13-entry View Mode dropdown
and pick it out, or reach it as an accidental side effect of toggling `Ecoregions (E)` off (its
toggle lands on `Biome` specifically). Added a **"Biome view (5)"** toggle-styled button directly
under the dropdown — outside the scrollable body, so it's visible immediately without scrolling —
that just sets `mode = ColorMode::Biome` (matching the plain `5` key, no side effects, works from
the very start of World Creation). Purely additive; the dropdown entry and `5` key are unchanged.
`src/render` only (`Toolbar.cpp`), no save-format change.
