fix(Icons): sync icon catalog with refreshed Line SVGs (#3080)

### 🎯 Goal

Sync the SDK icon exports with the refreshed Phosphor Line icon catalog
and align icon naming with the new conventions.

### 🛠 Implementation details

- **Updated `IconArrowDown`**: replaced old 16×16 filled path with the
20×20 Line stroke variant (removed `viewBox` override)
- **Updated `IconThread`**: replaced bubble-speech shape with the new
rectangular thread icon from the refreshed catalog
- **Renamed `IconLayoutAlignLeft` → `IconSidebar`**: matches
`sidebar.svg` in the Line set; updated all usages across
`ChannelHeader`, `ChannelListHeader`, `ThreadHeader`, `ThreadListHeader`
- **Renamed `IconThunder` → `IconBolt`**: matches `bolt.svg` in the Line
set; updated usages in `CommandChip` and example app
- Old names preserved as `// was:` comments for debugging
