Code Review

This pull request refactors the settings pages to move item values like name, email, and language to the right side of the tile, which improves the layout and alignment with the new design. The changes are implemented by introducing a value property in OmiSettingsTile and _buildSettingsRow widgets. The implementation is mostly correct, but I've found a layout bug in OmiSettingsTile where spacing is missing when both a value and a trailing widget are provided. My review includes a suggestion to fix this and simplify the layout logic.
