mAi: #110 - t-paliad-278 — 3-column date-range picker (Past/NOW/Future, closeness-to-NOW sort)

Restructures atlas's #79 horizontal row into 3 vertical columns: Past
(left), NOW (middle), Future (right). Each column sorts by closeness
to NOW (closest at top, farthest at bottom) — the picker now reads as
a spatial map of time around the current moment instead of a flat
horizontal fan.

Layout

  Vergangenheit          ⌖              Zukunft
  Letzte 7 Tage          Heute          Nächste 7 Tage
  Letzte 30 Tage         Alles          Nächste 30 Tage
  Letzte 90 Tage                        Nächste 90 Tage
  Ganze Vergangenheit                   Ganze Zukunft

Changes

- date-range-picker.ts — renderPanel builds .date-range-grid with
  three vertical .date-range-col children. Past column iterates
  PAST_HORIZONS reversed (past_1d → past_all top-to-bottom). NOW
  column hosts next_1d ("Heute") + any ("Alles") plus a ⌖ glyph
  header. Future column iterates NEXT_HORIZONS minus next_1d (which
  moved to NOW). Legacy "all" horizon still lights up the Alles chip
  for saved-Custom-View back-compat.
- global.css — replace .date-range-row/.date-range-fan/.date-range-
  center{,-btn,-glyph,-label} with .date-range-grid + .date-range-col
  + .date-range-col-heading. Chips stretch to 100% column width for a
  clean vertical stack. Panel widened from 32rem to 34rem so "Ganze
  Vergangenheit" never wraps. Mobile (max-width 540px) collapses the
  grid to a single column, preserving in-column sort.
- i18n.ts — next_1d label fixed from "Morgen"/"Tomorrow" to "Heute"/
  "Today". next_1d's bounds are [today, tomorrow) = single-day today,
  so the prior label was semantically wrong; renaming aligns the
  label with the bounds and matches m's "Heute" spec for the NOW
  column.
- axes.ts — DEFAULT_TIME_PRESETS updated to match m's spec (4 past +
  Heute + Alles + 4 future + custom). projects-detail.ts continues
  to override via timePresets for its past-only Verlauf surface.

12 horizon values in the union remain unchanged — PAST_HORIZONS /
NEXT_HORIZONS registries and parseURL still accept past_1d / past_14d
/ next_14d for back-compat with saved URLs; the default picker UI
just no longer surfaces chips for them. Surfaces that want the
finer granularity can opt back in via timePresets.

Verification

- bun test src/client/date-range-picker-pure.test.ts — 38 pass
- bun run build — i18n + branding + bundle clean
- go build ./... — clean
- go test ./internal/... — pass
