Fix accent-sensitive toggle state desync on database open

EntrySearcher was always initialized with accentSensitive=true
(constructor default), ignoring the user's saved config. Due to a
signal/multiplexer race in the database open sequence, the config
value from the UI toggle never reached the new DatabaseWidget. Now
read the config directly at construction time.
