fix(ui): Fix vertical text in metadata panel

Removed TextWrapWord setting from metadata value labels that was
causing text to wrap character-by-character in constrained space,
making the filename and other metadata appear vertically.

Text now flows naturally without wrapping, fixing the display issue
shown in the screenshot.
