refactor(ui): alert rows are two lines of text — the heading line was redundant

Creator: system messages are limited to two lines; the label above the message ('STEAM ID NOT
PRESENT', 'STREAM') was repeating what the row already said and pushing the stack past its budget.

AttentionAlert loses Label; rows render Text only. The licence row is now exactly:
    Steam ID Limit: 30fps
    Click for More Info
(60fps with a close control once owned). Rows are identified by Id internally, so nothing in the UI
depends on the removed text. Tests updated to assert position/text rather than the heading.
