변경 내용

• Replaced the phone form inline country overlay with a dedicated full-page selector.
• Kept search visible but unfocused so scrolling is the default interaction.
• Reused existing localized country search, selection, and national phone reformatting behavior.
• Added full-page back behavior and excluded the selector from bottom navigation.
