feat(grid): stop bars at the last symbol and shade today's column

- bar line begins/ends at a glyph centre — no stub past the first/last symbol
- glyph halos so the bar passes behind, not through, the symbols
- today's week is a shaded column instead of a vertical rule
- widen week columns so date labels stop colliding
- drop "slip" wording from the legend
