Andreas Kling f6e755506d LibWeb: Check weak pointer liveness in Database::for_key_and_name() ...

The database map stores GC::Weak<Database> entries. When the GC
collects a Database, the weak pointer goes null but the map entry
remains. The old code dereferenced the weak pointer without checking
liveness, causing a null reference binding (UBSan).

Fix this by checking ptr() before dereferencing, and cleaning up the
stale map entry if the database was collected.
