/**
 * Global guest-feedback defaults (#1044).
 *
 * Before this module the creation defaults lived in four places that had
 * already drifted: the admin create route's destructuring defaults, the v1
 * create route's hard-coded insert (which omitted `allow_reactions`
 * entirely), getEventFeedbackSettings()'s no-row fallback, and the migration
 * column defaults. Pinned here:
 *
 *  - with no app_settings rows, the built-in fallbacks apply (so installs
 *    that never open Settings > Events keep behaving exactly as before)
 *  - a stored global overrides its fallback, whether it was written as a JSON
 *    boolean, a bare "true"/"false" string, or SQLite's 0/1
 *  - garbage in a settings row falls back rather than writing null into a
 *    boolean column
 *  - an explicitly-sent body value always beats the global
 *  - keybind_mode only accepts the known schemes
 *  - getEventFeedbackSettings()'s no-row fallback reads the same globals
