feat: add --no-media flag to disable media display

- Introduced a new "no_media" boolean in ColumnsArgs to capture the
  --no-media flag.

- Updated NoteOptions to include a setting for hiding media, configured
  from parsed arguments.

- Refactored Damus to consolidate note options (textmode, scramble, and
  no-media) into a single NoteOptions field.

- Modified navigation UI rendering to pass the unified note_options.

This change allows users to disable media display via the --no-media flag.
