Use configured timezone throughout codebase

- Add config/timezone.go with timezone utilities:
  - SetDisplayTimezone(), GetDisplayTimezone()
  - Now(), Today() - current time/date in display TZ
  - ParseDateInDisplayTZ(), ToDisplayTZ() - parsing helpers

- Initialize timezone at startup in main.go

- Update all datetime logic to use configured timezone:
  - handlers/handlers.go - all time.Now() calls
  - handlers/timeline.go - date parsing
  - handlers/timeline_logic.go - now calculation
  - models/atom.go - ComputeUIFields()
  - models/timeline.go - ComputeDaySection()
  - api/plantoeat.go - meal date parsing
  - api/todoist.go - due date parsing
  - api/trello.go - due date parsing

This ensures all dates/times display correctly regardless
of server timezone setting.

-# [FEATURE] Integrate terst.org start page and styling
-
-## Description
-Integrate terst.org start page widgets and visual styling.
-
-## User Story
-As a user, I want the dashboard to incorporate my terst.org start page widgets and match its visual styling for a unified experience.
-
-## Technical Context
-- Two aspects: visual styling + widget integration
-- Requires understanding terst.org's current design system and widget architecture
-- May need API access or scraping depending on terst.org implementation
-
-## Test Strategy
-
-### E2E Test (Red)
-```
-1. Load dashboard
-2. Assert color scheme matches terst.org (primary colors, fonts)
-3. Assert expected widgets render (TBD based on widget inventory)
-```
-
-## Proposed Approach
-
-### Phase 1: Visual Styling
-1. **Audit terst.org design:**
-   - Extract color palette (primary, secondary, accent)
-   - Identify fonts and typography scale
-   - Note spacing/layout patterns
-2. **Update Tailwind config:**
-   - Add terst.org colors to theme
-   - Update default styles to match
-3. **Apply to existing components**
-
-### Phase 2: Widget Integration
-1. **Inventory terst.org widgets:**
-   - What widgets exist? (clock, weather, links, etc.)
-   - How are they implemented? (static HTML, JS, API-backed?)
-2. **Integration options:**
-   - Option A: Embed via iframe (quick but limited)
-   - Option B: Recreate widgets natively (more work, better integration)
-   - Option C: API calls to terst.org backend (if available)
-3. **Implement priority widgets first**
-
-## Discovery Required
-- [ ] Access terst.org to inventory widgets
-- [ ] Extract color palette and design tokens
-- [ ] Determine widget data sources
-
-## Affected Components
-- `tailwind.config.js` (theme colors)
-- `web/static/css/` (global styles)
-- `web/templates/index.html` (widget containers)
-- `web/templates/partials/` (new widget partials)
-- Potentially `internal/handlers/` (widget data endpoints)
-
-## Definition of Done
-- [ ] Color scheme matches terst.org
-- [ ] Typography matches terst.org
-- [ ] Priority widgets integrated
-- [ ] Responsive layout preserved
-- [ ] E2E test verifies styling
