fix: normalize bold top nav bar titles to default weight

The Buzz relay group (community) top bar and its sub-screens (members,
threads, browse, channel list), the Buzz canvas, geohash chat/new/teleport
screens, the single-URL and single-geohash viewers, and the Marmot group
chat all forced FontWeight.Bold (geohash chat also titleMedium) on their
top-bar titles, while every sibling channel header — DM rooms, public
chats, ephemeral chats, live activities — and the shared TopBar wrappers
render the Material3 titleLarge default at normal weight.

Drop the bold (and size) overrides so all top nav bar titles share one
consistent treatment.
