Summary:
This adds query parameters useful for tailoring the Grist experience, with an eye to embedding.
Setting `style=light` removes side and top bars, as a first pass at a focused view of a single document page (this would benefit from refining).
Setting `embed=true` has no significant effect just yet other than it restricts document access to viewer at most (this can be overridden by specifying `/m/default`).
Test Plan: added tests

Summary:
- Hides left and right panels and the top bar
- Hides cursor and active-section highlight
- Hides "=" icon on formulas
- Nudges browser to include background for row/column headers, which is not
otherwise included.
Still only what's visible is printed (e.g. large tables not paginated).
Test Plan: Tried a few pages manually on Firefox and Chrome.
