v115: Use existing FAB for island posts with island_username context

- FAB (+) button now context-aware - includes island_username when on island
- PostComposer accepts islandUsername prop and includes in payload
- Removed custom post buttons from island terrain view
- Global __activeIslandContext set when viewing an island
- App.jsx handles sw:openPostCreator event for island posts
