Utilize SetFormattedText

This change updates several text setters to use `SetFormattedText` instead of passing `string.format(...)` into `SetText`. It also switches a few regex captures from `string.find` to `string.match` for cleaner capture handling, and replaces explicit width/height setters with `SetSize` in the first-run dialog for consistency.
