Hard delete applications, nest installer packages, detect PE versions

Soft delete left orphaned executables on disk and let a deleted name collide
with a fresh import, so delete is now a hard delete that removes the
associated files. The destructive paths (delete, revert-to-record) require a
typed OK because neither can be undone.

Installers keep their filename at import and nest per application/version,
which stops repeat imports doubling up. Version now comes from the same PE
detection the endpoints agent uses; when no version can be read the caller is
asked for one rather than silently storing a blank.

Applications also surface Version and a monitorable toggle, with launch path
and process name required only while monitorable is ticked. Fleet shows the
PC alias, matching PC Details.
