feat(react-sdk): Migrate call layouts

[jdimovska]

💡 Overview

Migrates the four call layouts onto the design tokens: PaginatedGridLayout, SpeakerLayout, PipLayout and LivestreamLayout.

The first three are value-for-token swaps with no visual change. LivestreamLayout is also realigned to its Figma spec, so that one does look different.

📝 Implementation notes

LivestreamLayout now follows the Figma Livestream Tile spec:

• the scrim behind the overlay bar is gone — the live badge, viewer count, duration and speaker name each carry their own chip
• the bar is a fixed 48px tall, instead of 10% of the player height clamped to 40–70px
• the live badge gained a blinking dot
• mute and fullscreen use the Button primitive instead of bare <span>s

Everywhere else, only literals that map exactly onto a token were swapped. Values with no matching token were left as they are rather than snapped to the nearest one — the PiP avatar sizes (60 / 45 / 35 / 25px) are the main example.

Also in here: a poll icon class, and a fix for the speaking border in dogfood's PiP grid, whose corners were being clipped because its radius didn't match the tile's.
