Extracted the folds-native dropdown (Button+PopOut+Menu) from General.tsx into a
shared components/settings-select/SettingsSelect.tsx, and used it to replace raw
native <select> elements (which render OS-styled and broke under non-default
themes via colorScheme:'dark'):
- Profile "auto-clear after" select
- PushRuleEditor add-rule mode select (dropped the now-unused handleModeChange)
The form-tied timezone <select> in Profile is left for a follow-up (it's wired
to native form submission + a disabled state and needs more care).
