Zen Dark theme, revised cards, unified sheets, speed dial, colour and category settings

[mapgie]

Summary

Implements the consolidated "Cozy Cream + Zen Dark" design handoff (turns 5a to 8a). The handoff package itself is checked in under docs/design/cozy-cream.

• Zen Dark theme. The Cream palette's dark scheme now carries the handoff's token column (warm charcoal-green ground, one-step-lighter cards, sage/rose/amber/lavender lifted for dark). Non-Material tokens (nav ground and inactive ink, faint ink, sort-pill outline, NFC button, scrim, sheet blocks) live in a DashTokens CompositionLocal; other palettes derive them from their own scheme. Dark ships as the default brightness per 8a.
• Palette model. Seven swatches with per-brightness spine/text/tint tones (Swatch.kt), severity colours resolved through LocalSeverityColors, and a JVM test that pins every text/tint, text/card and text/ground pair at 4.5:1 in both themes.
• Lucide icons parsed from SVG path data (LucideIcons.kt), one glyph per category with keyword defaults; the Chores tab is the house-with-check glyph.
• Revised cards (5a): 16dp radius, 5dp spine, 38dp icon chip, meta line under the title, avatar left of the due badge, no progress bar. The done toggle keeps a 44dp touch target around the 38dp visual.
• Chores and Tasks lists: identical header row (search, owner, zen, group/flat); NFC scan button beside the Chores title replacing the in-list hint card; a sort pill that names key and direction in words with a picker sheet (persisted per list); category grouping in catalog order with section counts; the summary bar ("7 chores · 1 hidden", "Archived ›" / "Done ›").
• Unified Log/Done sheets (6a): header, DONE control (Just now / Earlier today / Pick…), Cancel + sage action, utility row (Calendar · Pin · Remind · Tag · Edit), history block with an inline Undo chip on the latest log and an "All ›" link; tasks get Remind (opens the reminder sheet linked to the task) and a Notes block.
• Unified Edit sheets (7a): the title is the field, one grouped settings card with compact controls (category value chip with picker, owner avatar row, repeat stepper with direct entry, priority segments, due and remind value chips, NFC tag row), notes block for tasks, tertiary Add to calendar · Share · Archive/Delete. The New chore sheet is the same component (replaces AddChoreSheet). Chore category can now be edited. Dirty guard retained on every dismiss vector.
• Speed dial over the whole screen including the bar; the active tab's item sits closest to the thumb, the rest follow the Quick add order setting.
• Settings › Colours and Settings › Categories (new screens), backed by new settings keys and a per-device category catalog (order, icon, colour) in DataStore; rename and delete update every chore and task in Supabase (delete moves them to General).

Dropped / needs decision

Nothing functional was removed silently. Items that could not be built exactly as drawn, or where the handoff left a decision open:

1. Sheet primary-action colour (8a open question). Built with sage in both themes (matches the FAB and "Log it"); Cozy Cream mock-ups show purple. One-line change in SheetPrimaryRow if you prefer purple in light.
2. Zen Dark as default brightness. Users who never chose a brightness will now get dark (the stored preference, if any, is respected). Say the word and I'll keep SYSTEM as the fallback instead.
3. Due-countdown header toggle. The chore badge now always shows the countdown ("35d over", "1d left") and the sort part of that toggle is the sort pill's "pressure · worst first". The toggle and its showDueCountdown preference were removed; the absolute last-done date moved into the card meta line and the sheet header.
4. Remind row on the chore edit sheet. Chores have no reminder column; reminders for a chore stay reachable from the Log sheet's Remind action (creates a linked reminder), so the row is omitted on chores rather than faked.
5. Notes on chores. The tags table has no notes column, so the notes block exists on the task sheet only.
6. Tag label. There is no separate label field for a tag; the sheet shows the tag ID in the tag-label slot ("no label" when blank).
7. Tasks All/Active chips in the 5a Tasks mock-up were not reinstated; 0.26.0 deliberately removed them in favour of the collapsible Done section, which the summary bar's "Done ›" now jumps to.
8. Reminders/Memos list and the 4a settings screens (Appearance, Display, Reminders & alerts, About) only pick up the theme, card and icon changes; they were not redesigned in this handoff.
9. Category-mode colours for unstyled categories fall back to a stable per-name swatch (so groups still differ) until the user picks one.

Tests

ChoreUiStateTest, TaskUiStateTest and ChoreModelTest cover the sort pill orders in both directions, category grouping order, summary labels, overdue count and the new due badge. SwatchContrastTest and CategoryCatalogTest are new. The container has no Android toolchain, so CI is the build check for this PR.
