Fix: improve formatting for long usernames

[21Ladder]

Description

Closes: #319
This PR fixes the formatting issue where long usernames in the GeohashPersonItem row were causing strange wrapping and misaligned text.

• Changed from multiple Text composables in a Row to a single AnnotatedString inside one Text.
• Enabled line breaking and hyphenation for long/no-space names.
