fix(inbounds): only reset id sequence when all inbounds are deleted

Commit 80110f9 realigned sqlite_sequence to MAX(id) after every delete,
which recycled freed ids and let a newly added inbound take an old
inbound id. Now the sequence row is cleared only when the table is empty,
so the counter keeps climbing while any inbound remains and existing ids
are never reused. Still guarded behind !IsPostgres().
