Fix dashboard UI issues: tabs visibility, loading indicators, timezone support

Fixed three UX issues identified during testing:

1. Tab Visibility Fix:
   - Before: White tabs on white background (invisible until hover)
   - After: Gray background (#e5e7eb) with dark text
   - Active tab: Blue background with white text
   - Hover state: Darker gray for feedback

2. Loading Indicators:
   - Added CSS spinner animation
   - Shows spinner + 'Loading...' text while fetching data
   - Applied to both loadSchedules() and loadResults()
   - Better UX - users know data is being retrieved

3. Timezone Support:
   - Added timezone selector dropdown in one-time schedule form
   - Options: Local browser time (default), UTC, major timezones
   - Automatically converts selected timezone to UTC for API
   - Helper text: 'Time will be converted to UTC for storage'

UI Improvements:
- Tabs now have font-weight: 500 for better readability
- Hover states on inactive tabs
- Loading state prevents confusion during API calls
- Timezone dropdown with common options

Updated README to highlight new features:
- Timezone support in dashboard
- Loading indicators
- Status badges
