fix: guard savePrefs with dirty flag in BotScreen and DashboardConfigScreen

Browse Source 
BotScreen and DashboardConfigScreen were calling savePrefs() on every
exit regardless of whether any setting changed. Add _dirty flag set only
on actual value changes (toggle, channel select, keyboard confirm,
field cycle), reset on enter().
