mitchross ebc838fa9d Add global timezone/12h-24h setting and improve satellite selection
Global time preferences (Settings > Display > Time & Timezone):
- InterceptTime utility in core/utils.js with timezone + 12h/24h support
- Timezone options: UTC, Local, Eastern, Central, Mountain, Pacific
- Time format: 12-hour (AM/PM) or 24-hour toggle
- Defaults to US/Eastern + 12-hour
- Header nav clock updates to use selected timezone and format
- Weather satellite mode delegates to global InterceptTime
- Settings persist via localStorage, change listeners notify all modes

Weather satellite improvements:
- Satellite dropdown defaults to "All Meteor Satellites" showing all passes
- Can still filter to specific satellite (M2-3, M2-4, M2-4-80K)
- Capture button on pass cards auto-selects the correct satellite
