Expand the system symbol catalogue with 199 new symbols

The curated SystemSymbol catalogue shared by Objo apps and Studio's own interface is growing from 229 to 428 symbols. The additions include:

• Weather icons (sun, moon, rain, snow, thunderstorm, and more)
• More chart types for dashboards (area, histogram, funnel, scatter, treemap, and more)
• User presence indicators (available, away, do-not-disturb, offline, blocked)
• Reactions (heart, thumbs up/down, emoji faces)
• Shapes, alignment, and z-order tools for drawing apps
• More camera, video, and image icons
• Sign-in/sign-out, restart, rotate, translate, and other everyday actions
• Wi-Fi and battery signal levels
• More file/document states, database states, mail and chat states, and status icons

Symbols remain semantic, scalable, and theme-aware, and continue to render at consistent sizes for each presentation context.
