Rework MPV Options for macOS-native look

Convert the main view to shared SettingsFormContainer/Section helpers,
drop the DisclosureGroup in favor of a single always-visible Default
Options section with monospaced trailing values, and redesign the
Add/Edit MPV option sheets on macOS as native dialogs with a Grid
layout, clearer footers, and keyboard-shortcut actions.
