The chart X axis used dataMin/dataMax domain, compressing the view to
only the data present. A 6h view with 1.5h of data looked like 1.5h.
Pin the X axis to the full selected time range, pad data edges so the
line extends to both ends, and connect through nulls for a continuous
line.

Closes#75
Problem: The backend stores timestamps in UTC, but when sending them to the frontend without timezone indicators, JavaScript interprets them inconsistently. Users saw UTC times displayed directly instead of converted to their local timezone (e.g., America/New_York).
Solution implemented:
1. Created /frontend/src/utils/date.ts with utilities:
- parseUTCDate(dateStr) - Parses backend timestamps as UTC by appending 'Z' to strings without timezone indicators
- formatDate(dateStr, options) - Formats UTC timestamps to local date/time
- formatDateOnly(dateStr, options) - Formats UTC timestamps to local date-only
2. Updated 15 frontend files to use the new utilities:
- ArchivesPage.tsx - Archive cards and list view dates
- PrintersPage.tsx - Last print date
- SettingsPage.tsx - API key last used date
- QueuePage.tsx - Scheduled print times
- ProjectDetailPage.tsx - Due dates and timeline
- ProfilesPage.tsx - Relative time display
- CalendarView.tsx - Calendar grouping by local date
- NotificationLogViewer.tsx - Log timestamps
- NotificationProviderCard.tsx - Last success date
- AMSHistoryModal.tsx - Chart data timestamps
- FilamentTrends.tsx - Usage data grouping
- PrinterQueueWidget.tsx - Queue item dates
Implement comprehensive theme customization with independent settings for
dark and light modes:
- Style layer: Classic (clean shadows), Glow (accent-colored glow effects),
Vibrant (dramatic deep shadows)
- Background layer: Neutral, Warm, Cool (light mode); plus OLED, Slate,
Forest (dark mode only)
- Accent colors: Green, Teal, Blue, Orange, Purple, Red
All combinations work independently (e.g., Glow + Forest + Teal). Settings
sync across devices via database and show toast confirmations on change.
Backend:
- Add 6 new settings fields (dark_style, dark_background, dark_accent,
light_style, light_background, light_accent)
- Add integration test for theme settings API
Frontend:
- Refactor index.css with 3-layer CSS variable system
- Update ThemeContext for dual-mode theme management
- Add Appearance section to Settings page with 6 dropdowns
- Update components for new ThemeContext API
- Add database model for storing AMS sensor history (humidity, temperature)
- Record sensor data every 5 minutes via background task
- Add API endpoint to retrieve history with min/max/avg statistics
- Create AMSHistoryModal component with Recharts line charts
- Make humidity/temperature indicators clickable to open history
- Support time range selection (6h, 24h, 48h, 7d)
- Show threshold reference lines on charts (Good/Fair levels)
- Add configurable data retention (default 30 days) in Settings
- Auto-cleanup old data daily
- Fix dark theme styling in modal using inline styles
- Add Escape key to close modal
